1 John, Lesson 4

Lesson 4


Heavenly Father, we come before You again to study Your word. We pray that You will speak to us through the pages of scripture. We pray for illumination and enlightenment by the Holy Spirit. We pray for eyes to see and ears to hear, in Jesus’ name, Amen.

1 John 2: 12-29, do not love the world

VV 12-14, 12 I write to you, little children, Because your sins are forgiven you for His name’s sake. 13 I write to you, fathers, Because you have known Him who is from the beginning. I write to you, young men, Because you have overcome the wicked one. I write to you, little children, Because you have known the Father. 14 I have written to you, fathers, Because you have known Him who is from the beginning. I have written to you, young men, Because you are strong, and the word of God abides in you, And you have overcome the wicked one.

John wrote to three categories of people, little children in the faith, new believers, fathers in the faith, mature believers, and young men in the faith, those in between the two extremes. He commended them because their sins were forgiven, they knew Christ, they had overcome satan, they were strong in the faith, and they knew the word of God.

VV 15-17, 15 Do not love the world or the things in the world. If anyone loves the world, the love of the Father is not in him. 16 For all that is in the world, the lust of the flesh, the lust of the eyes, and the pride of life, is not of the Father but is of the world. 17 And the world is passing away, and the lust of it; but he who does the will of God abides forever.

Greek for love in all of 1 John is “agape”, which means the divine love of God for people. Greek for world is “kosmos”, which means the earth. We do not love or be too attached to the things of the world. Our real citizenship is heaven although we are living on earth. Greek for passing away is “parago”, which means disappear. This world will disappear soon as Jesus’ second coming is imminent. The lust of the flesh speaks of the desires of the flesh. The lust of the eyes speaks of covetousness. The pride of life speaks of arrogance. Satan tempted Jesus on these on the Mount of temptation but Jesus overcame them by the word of God. Satan tempted Jesus to satisfy his hunger by changing stones to bread, (the lust of the flesh), showed Him the Kingdom of the world and bow down to him, (lust of the eyes), and defy God by jumping off the pinnacle of the temple (pride of life).

V 18, Little children, it is the last hour; and as you have heard that the Antichrist is coming, even now many antichrists have come, by which we know that it is the last hour.

John warned his audience and us about the imminent second coming of Christ and the coming of the Antichrist onto the world scene. The Antichrist is a ruthless dictator who will rule the earth during the last seven years of world history called the tribulation. He is also called the beast, the man of lawlessness, and the man of perdition.

VV 19-23, 19 They went out from us, but they were not of us; for if they had been of us, they would have continued with us; but they went out that they might be made manifest, that none of them were of us. 20 But you have an anointing from the Holy One, and you know all things. 21 I have not written to you because you do not know the truth, but because you know it, and that no lie is of the truth. 22 Who is a liar but he who denies that Jesus is the Christ? He is an antichrist who denies the Father and the Son. 23 Whoever denies the Son does not have the Father either; he who acknowledges the Son has the Father also.

They who “went out from us, but we’re not of us”, speaks of the false heretic gnostic teachers. The anointing of the Holy Spirit should enable Christians to discern truth from lies. Anyone who denies Jesus as the Christ, and the Father as God is an antichrist. Whoever denies Christ, denies the Father. Whoever acknowledged Christ, acknowledged the Father.

V 24, Therefore let that abide in you which you heard from the beginning. If what you heard from the beginning abides in you, you also will abide in the Son and in the Father.

John encouraged his disciples and us to abide in Christ and in the Father.

VV 25-27, 25 And this is the promise that He has promised us, eternal life. 26 These things I have written to you concerning those who try to deceive you. 27 But the anointing which you have received from Him abides in you, and you do not need that anyone teaches you; but as the same anointing teaches you concerning all things, and is true, and is not a lie, and just as it has taught you, you will abide in Him.

We have the promise of eternal life from Christ. John warned his audience and us not to be deceived by the false teachings of the heretic gnostic teachers. If we abide in Christ His anointing on us reveals and teaches us all things.

VV 28-29, 28 And now, little children, abide in Him, that when He appears, we may have confidence and not be ashamed before Him at His coming. 29 If you know that He is righteous, you know that everyone who practices righteousness is born of Him.

John encouraged his audience and us to abide in Christ and to have confidence in His second coming because. Christ is righteous and those who practice righteousness are His children.


We are not to hold too tightly to the things of the world because we do not belong to the world. We are not immortal and the world will not last forever. Our real citizenship is heaven. One day, we will be with Christ in heaven until eternity. Our years of earthly existence are insignificant compared to eternity. We are to invest in the things of the kingdom that will last into eternity.


Heavenly Father, we confessed that we are sinners. We pray for forgiveness of sins and obedience to Your calling. Help us not to cling on tightly to the things of the world but cling to the things of the kingdom. We pray for kingdom perspective, in Jesus’ name, Amen.

1 John, lesson 3

Lesson 3


Heavenly Father, we acknowledged that You are Emanual, Lamb of God, Lion of Judah, city of refuge, shepherd of our souls, and captain of our souls. We pray for soft, faithful, obedient, teachable, and sensitive spirits to tap into Your goodness, grace, and love, in Jesus’ name, Amen.

1 John 2: 1- 11, The tests of Knowing Christ

VV 1-2, 1 My little children, these things I write to you, so that you may not sin. And if anyone sins, we have an Advocate with the Father, Jesus Christ the righteous. 2 And He Himself is the propitiation for our sins, and not for ours only but also for the whole world.

John, the last surviving apostle of Christ, addressed his audience tenderly as little children. As Christians, we are not to habitually sin but if we sin, we have Jesus Christ as our Advocate with the Father. Greek for advocate is “parakletos’, which means counselor or defense attorney. Greek for propitiation is “hilasterion” which means the mercy seat. The Mercy Seat was the golden cover on the Ark of the Covenant which was kept in the Holy of Holies. Before the destruction of the temple, the high priest enters the Holy of Holies once a year on Yom Kippur day, to sacrifice a lamb and splash the blood of the lamb onto the mercy seat as atonement for the sins of the Israelites for 1 year. On Good Friday, Jesus Christ died on the cross as a substitutionary atonement for our sins. He meets us on the mercy seat of the ark of the covenant to forgive our sins.

VV 3-6. 3 Now by this, we know that we know Him, if we keep His commandments. 4 He who says, “I know Him,” and does not keep His commandments, is a liar, and the truth is not in him. 5 But whoever keeps His word, truly the love of God is perfected in him. By this we know that we are in Him. 6 He who says he abides in Him ought himself also to walk just as He walked.

The tests of knowing Christ are obedience to His commands, love God, and love people. We cannot claim to know Christ if we do not obey His commands. Christ is truth. The test of knowing Christ is to walk in truth. Christ is love. Another test of knowing Christ is to walk in love, vertical love for God, and horizontal love for people. Greek for abide is “meno”, which means remain or endure. If we remain in Him, we are to obey Him and conduct our lives according to His commands.

VV 7- 8, 7 Brethren, I write no new commandment to you, but an old commandment which you have had from the beginning. The old commandment is the word which you heard from the beginning. 8 Again, a new commandment I write to you, which thing is true in Him and in you, because the darkness is passing away, and the true light is already shining.

The old commandment is from the Old Testament, love the Lord with all your heart, with all your soul, and with all your strength, Duet 6:4. The new commandment is from the New Testament, to love another as Christ loved us, John 13:34. The true light of Christ’s righteousness had come to remove the darkness of evil in the world, John 1:5.

Deut 6:5, “You shall love the Lord your God with all your heart, with all your soul, and with all your strength”.

John 13:34, “A new commandment I give to you, that you love one another; as I have loved you, that you also love one another”.

John 1:5, “And the light shines in the darkness, and the darkness did not comprehend it”.

VV 9- 11, 9 He who says he is in the light and hates his brother, is in darkness until now. 10 He who loves his brother abides in the light, and there is no cause for stumbling in him. 11 But he who hates his brother is in darkness and walks in darkness, and does not know where he is going, because the darkness has blinded his eyes.

Christ is light. Another test to know Christ is to walk in the light of Christ. We are to walk in the light of Christ and love our brother. If we hate our brother we are in darkness and deception and the light of Christ is not in us. Light is symbolic of Christ, truth, righteousness, and goodness. Darkness is symbolic of satan, deception, sin, and evil.


We are not to sin habitually, but if we sin, we are to come before Jesus Christ in confession and repentance. If we confess our sins, Christ is faithful and just and will forgive and cleanse us of all our unrighteousness. We are to walk in obedience, in truth, in love, in light, in the Holy Spirit, and in Christ. These are the tests of knowing Christ.


Heavenly Father, we confess that we are sinners saved by grace. We pray for forgiveness of sin, justification, salvation, sanctification, and eternal life. We pray for divine guidance and enablement to walk in obedience, in Christ, in the Holy Spirit, in truth, in light, and in faith, in Jesus’ name, Amen.

1 John, Lesson 2

Lesson 2


Heavenly Father, we acknowledged that You are the bright morning star, lily of the valley, rose of Sharon, ancient of days, kinsmen redeemer, Holy One of God, Holy One of Israel, and Holy One of Jacob. We pray for open, receptive, soft, obedient, and teachable spirits, in Jesus’ name, Amen.

1 John 1: 5-10, Walk in the light of Christ

V 5, This is the message which we have heard from Him and declare to you, that God is light and in Him is no darkness at all.

Jesus is the word of God. Greek for word is “logos”, which means message. John declared to his readers and us, that he and the apostles had heard from Jesus, the message of God. Jesus is the light of life who shines His light into the dark world. Jesus is light of the world and whoever walks with Him will not stumble in darkness, 1 John 1:1, John 1:4, John 8:12, John 9:5.

1 John 1:1, “That which was from the beginning, which we have heard, which we have seen with our eyes, which we have looked upon, and our hands have handled, concerning the Word of life”.

John 1:4, “In Him was life, and the life was the light of men”.

John 8: 12, Then Jesus spoke to them again, saying, “I am the light of the world. He who follows Me shall not walk in darkness, but have the light of life.”

John 9:5.  “As long as I am in the world, I am the light of the world”.

V 6, If we say that we have fellowship with Him, and walk in darkness, we lie and do not practice the truth.

We cannot have fellowship with Jesus if we continue to live in sin, continue to walk in darkness, deception, and falsehood. The light of Jesus removes darkness, exposes deceptions, lies, and falsehood. We cannot hide anything before Jesus because He is an all knowing omniscient God, Hebrews 4:13.

Hebrews 4:13, “And there is no creature hidden from His sight, but all things are naked and open to the eyes of Him to whom we must give account”.

V 7, But if we walk in the light as He is in the light, we have fellowship with one another, and the blood of Jesus Christ His Son cleanses us from all sin.

If we walk in the light of Christ and are cleansed of sins, we can have fellowship with Him and with our fellow Christians.

VV 8-10, 8, If we say that we have no sin, we deceive ourselves, and the truth is not in us. 9 If we confess our sins, He is faithful and just to forgive us our sins and to cleanse us from all unrighteousness. 10 If we say that we have not sinned, we make Him a liar, and His word is not in us.

No one can claim to be sinless, for all had sinned and fallen short of God’s perfect standard, Romans 3:23. If we sin, we should come before Jesus, confessed and repent of our sin. Jesus is faithful and will forgive our sins and purifies us, 1 John 1:9. If we insist that we are sinless, we are not living in the truth of God’s words.

Romans 3:23, “for all have sinned and fall short of the glory of God”.

1 John 1:9, “If we confess our sins, He is faithful and just to forgive us our sins and to cleanse us from all unrighteousness”.


We are to walk in the truth of Holy Spirit. We are to be transparent before Him and not habitually sin. But if we sin, we are to confess our sin before Him and repent. We are to claim the promise of 1 John 1: 9 for the forgiveness of sin and cleansing.


Heavenly Father, we praise You and thank You because You are worthy to be praised. You are the name above all names, You are light and there is no darkness in You. We pray that You will help us to walk in the light of Christ, in Jesus’ name, Amen.

1 John

Lesson 1


Heavenly Father, we pray for wisdom to tap into Your knowledge through daily devotion, daily reading of Your Word, and daily Bible study. We pray for wisdom, knowledge, and understanding of scripture, in Jesus’ name, Amen.



Scholars agreed that apostle John, who wrote the gospel of John and Revelation, was the author of 1 John, 2 John, and 3 John. It was believed to have been written around 90 AD in Ephesus. John was the last remaining apostle of Christ and he was a very old man when he wrote 1, 2, and 3 John.


1 John was not written to any specific Church or individual. It was a cyclical letter written to a group of churches in the region around the city of Ephesus.

Occasion, setting, purpose :

John wrote 1 John to address the false teachers who came to deceive the Christians with the heretic teachings called Gnosticism. Gnosis in Greek means knowledge. These heretic gnostic teachers claimed that they had special knowledge on salvation that others did not have. The Gnostics believed that the soul is intrinsically good and the body is intrinsically evil. The Gnostics accept the Deity of Christ but reject the humanity of Christ. They believed that Jesus was hundred percent divine and zero percent human. They believed that when Jesus walked on the earth, He will not leave any footprint behind Him. There are two extreme forms of Gnosticism. One extreme is asceticism and denial of all physical pleasures of life. The other extreme is licentiousness and freedom to sin since the body is intrinsically evil and headed for destruction. John’s purpose was to refute the heretic teachings of the Gnostics and to bring the people back to correct theology.

1 John 1:1-4, John declared what he saw, heard, and handled

V 1, That which was from the beginning, which we have heard, which we have seen with our eyes, which we have looked upon, and our hands have handled, concerning the Word of life,

The beginning alludes to Genesis 1:1, “in the beginning, God created the heavens and the earth” and John 1:1, “in the beginning was the Word, and the Word was with God, and the Word was God”. John used the Word of life as a title for Jesus Christ, who pre-existed and self-existed from the beginning before creation, before time, before space, and before matter. John proclaimed that Christ is fully God and fully human. He could be seen, heard, touch, and handled. In the gospel of John, Christ could feel thirsty, hungry, tired, sad, and even wept.

VV 2-4, 2 the life was manifested, and we have seen, and bear witness, and declare to you that eternal life which was with the Father and was manifested to us, 3 that which we have seen and heard we declare to you, that you also may have fellowship with us; and truly our fellowship is with the Father and with His Son Jesus Christ. 4 And these things we write to you that your joy may be full.

Greek for life is “zoe” which means the God-given divine or eternal life. Greek for manifest is “phaneroo”, which means to make visible. Jesus, the word of eternal life, was made visible through the His incarnation. John and the other apostles witnessed, declared, seen, handled, heard, and fellowshipped with the incarnate word of life. God invites us into a fellowship with Him and His Son Jesus Christ so that our joy may be complete.


Jesus Christ is the pre-existing, self-existing, eternal Son of God. He is co-equal, co-divine, and co-eternal with the Father sharing the same Godhead. John testified that Jesus Christ is fully divine and fully man who could be seen, heard, and handled. John refuted the Gnostic’s claim that Jesus is one hundred percent divine and zero percent human.


Heavenly Father, we claim the promise of Isaiah 55:11, that Your word will not return to You empty but will accomplish what You desire and achieve the purpose for which You sent it. We pray for wisdom to understand, apply, and obey Your teachings, in Jesus’ name, Amen.

Memoirs of a Doctor, an extraordinary journey of faith across continents that will encourage, enlighten, and empower you to fulfill your God-ordained destiny! by Dr. Andrew C S Koh.


A 140 pages, softcover physical book.


Memoirs of a Doctor is the story of my life. This story began from my birthday on 11th January 1952 until my retirement day on 11th Jan 2020. The purpose of my memoir is to document my life story as a legacy for my family, relatives, and friends. The story traces back to the tough beginnings of the 1950s when life and society were very backward, when industrialization, computerization, social media, and automation were unheard of. Life was slow and leisurely, letters were sent and read through the postal service, and communication was slow, and perhaps inefficient by today’s standard. This book is divided into 8 chapters, each chapter describing a particular stage of my life, with photos relevant to each chapter and a poem before each chapter. The story unfolds with each chapter and culminates with the testimony of my retirement in 2020. There are certainly many valuable life lessons to be learned from a story covering a span of so many years. If any reader is inspired to trust in God, excel in life, and persevere in the face of adversity, this book would have achieved its purpose.


Bishop Ng Moon Hing, Anglican Bishop of West Malaysia

Indeed, a truthful and insightful journey of life a doctor, Dr. Andrew C S Koh. This is an easy and interesting book and when someone picks up to read, he will not put it down until the last page. A true, interesting, and colorful life story of an ordinary person who becomes a cardiologist with the help and guidance of the one and true God, Jesus Christ. This book indicates to us that though we may not believe or know God, He is always there planning and guiding our lives. The author wishes to share with his readers that when one does know this God, Jesus Christ, He will even more ready to prepare and usher him towards the direction where he can find security, meaning, blessings, and joy. The panoramic view of a village boy to a city doctor, interspersed with beautiful poems, has shown how an honest, innocent young person faced and swam in the ocean of many sophisticated and challenging turbulence. His faith in Jesus Christ has become an oasis for him in the world of struggles, unending expectations, and stressful pressures. A book I find great relief and comfort for the soul.

Dr. Robert, USA:

Dr. Koh provided glimpses of his life through the years in a short, loveable, and easy-to-read book. I enjoyed his reminiscing about the kind of life he used to live in the cities and villages in Malaysia before the arrival of social media. His varied experiences as a government, private, and military physician were a novelty to read as well. I would have wanted him to elaborate more on some of the key events in his life, so perhaps there’s room for a sequel or version 2.0?

Dr Wong Che Hoa, Malaysia:

A well-written Memoir by Dr. Andrew C S Koh, a personal friend for the past 30 years. It provides inspiration to all young aspirants who want to emulate Dr. Andrew‘s footsteps to success both professionally and spiritually. Congratulations on the well-written and meticulous recapture of your life history in words. May God bless you abundantly.

Dr. Kevin, Malaysia:

Such a sweet and colorful life you lead through with God being with you with or without your knowledge as He scripts your life. May God lead us through the current Covid storm. Amen and praise to Him!

Rev. Ng Wah Lok:

Pastor of Full Gospel Tabernacle, Sri Damansara, Malaysia

Principal of Tung Ling Seminary (1999-2019)

I found reading this book very inspiring as Dr. Andrew Koh shares stories about his childhood, education, a career in different towns, marriage and family, loss of friends, close encounter with paralysis, travels, and most of all his love for the Bible. The memoirs include some of his personal poems with the latest one about the Covid 19. Underlining the memoir is his faithfulness to God’s Word, and living a productive and impactful life. At the end of the reading, you will find that God has been his faithful guide and shield all through his life.

Dato KRA Naidu, Malaysia:

Memoirs of a Doctor is an excellent autobiography by Dr. Andrew C S Koh, my ex-student in MES Tanjong Malim way back in 1969. This book took me onto an extraordinary roller coaster ride through the time tunnel of history from 1952 to 2020 from Tanjong Malim across continents. It was undoubtedly an extraordinary journey of faith. It would be amazing if one has a chance to go back in time to live life differently, to change the course of history, and to rectify certain events. Going back in time is an enriching experience and at times painful. A memorable, well-written, enjoyable, and lovely memoir to touch lives, Congratulations.

Carol, Malaysia:

Dr. Koh has portrayed an excellent abstract of his life story defining significant times such as childhood and adolescence, and the times he was touched by the grace of God. It is an interesting book, full of the spices of life, touching, sad, and sweet reminiscences of his past that will stir the heart of any reader. It is extremely well-written with a few sweet little poems here and there. Passionate touches of God in his life give one great inspiration and encouragement to strive on.

Daniel Wong, Malaysia:

My sheep hears my voice and follow me. In a nutshell, Dr. Koh bears testimony to what the Word of God is saying to him even to this very day. There is no shadow of a doubt that he has heard the voice of the Lord Jesus our chief shepherd. Shalom. I am truly encouraged by the memoirs of Dr. Andrew Koh. Praise and glory to the Lamb of God. Amen.

Pastor Joshua Tan, Malaysia:

A very inspiring and encouraging masterpiece presented enthusiastically and passionately. Clearly, the hand of God is with Dr. Andrew C S Koh and transforming him from a nobody into a giant for the Kingdom of God. Go forth, the best is yet to come. May you continue to be a blessing to many via your writings and other endeavors.

Steven Heoe, Auckland, New Zealand:

Dr. Andrew C S Koh’s memoir is a beautiful narration of his life story and journey of faith. It is written in simple English and the book is easy to read. You will be encouraged and inspired, as I was, by his stories and his life as a Christian.
