Jacob’s Well

🎶 A Song Inspired by John 4

I’m delighted to share my new song, “Jacob’s Well,” a heartfelt worship piece inspired by the powerful encounter between Jesus and the Samaritan woman in John 4. This passage has always spoken deeply to me, and this song seeks to capture its timeless message of grace, transformation, and true spiritual thirst.

💧 The Story Behind the Song

, In John 4, we see Jesus meeting a woman at a well, a simple, everyday setting that becomes a place of divine revelation. What moves me most is how Jesus crosses boundaries, social, cultural, and spiritual, to offer “living water.” This living water is not physical but eternal, satisfying the deepest longing of the human soul.

While writing Jacob’s Well, I reflected on how often we search for fulfilment in temporary things, yet remain thirsty. The Samaritan woman’s journey, from confusion to revelation, from isolation to witness, inspired the emotional and spiritual flow of the song.

🎼 Musical Style and Mood

The song is written in a gentle, reflective worship style, with a melody that is easy to sing along to. I intentionally kept the structure simple and meditative, allowing listeners to linger on the message rather than be distracted by complexity. The music builds gradually, mirroring the unfolding conversation at the well.

🌿 Themes and Message

Jacob’s Well highlights several key spiritual truths:

  • God meets us where we are, even in unexpected places.
  • Jesus offers living water that satisfies the soul permanently.
  • Transformation leads to testimony, like the woman who ran back to her village to share the good news.
  • True worship is in spirit and truth, not confined to a place.

I hope listeners will hear not just a retelling of Scripture, but a personal invitation: Come to the Well. Drink deeply. Be changed.

💡 A Personal Reflection

Writing this song reminded me that we all have our own “wells”, places where we encounter God in quiet, ordinary moments. And just like the Samaritan woman, our past does not disqualify us from receiving His grace. Instead, it becomes part of our testimony.

🙏 Final Thoughts

My prayer is that Jacob’s Well will encourage you to draw nearer to Christ and experience the life-giving water He freely offers. May it also inspire you to share that joy with others.

“Whoever drinks the water I give them will never thirst.” John 4:14

Thank you for listening and journeying with me.

The Father who ran

Two men share a heartfelt hug on a city sidewalk at dusk.

A Song of Scandalous Grace

We have all heard the story of the Prodigal Son in Luke 15. We know the beats of the narrative. The rebellious son demands his inheritance, squanders it in a distant land, hits rock bottom in a pigpen, and decides to crawl back home begging to be a hired servant.

But there is a specific, radical moment in that scripture that completely flips the cultural norms of the ancient world upside down.

It’s the moment the Father ran.

My new song, “The Father Ran,” is born directly out of this profound, beautiful text. It is a musical reflection on the heart of a Father who doesn’t wait for us to clean ourselves up before He embraces us.

The Scandal of the Running Father

In ancient Near Eastern culture, an elder patriarch, a man of stature and wealth, never ran. It was considered deeply undignified. To run meant a man had to lift up his long robes, exposing his ankles, a deeply humiliating act in that society.

Yet, Luke 15:20 tells us:

“But while he was still a long way off, his father saw him and was filled with compassion for him; he ran to his son, threw his arms around him and kissed him.”

The Father didn’t walk. He didn’t wait on the porch with a lecture prepared. He didn’t demand an apology first. He cast aside his dignity, broke all the social rules, and ran to bridge the gap. He took the shame of the village upon himself to intercept his broken son before anyone else could condemn him.

Behind the Song

When I sat down to compose “The Father Ran,” I wanted the music and the lyrics to capture that breathtaking transition from the heavy, lonely isolation of the pigpen to the overwhelming, fast-paced joy of the Father’s embrace.

This song is for anyone who feels like they’ve wandered too far. It’s for the person who thinks their past is too messy, their mistakes are too loud, or that they’ve used up their second chances.

The message of this song is simple: God is not waiting to judge you; He is running to restore you.

The Good Samaritan

A Song about compassion that crosses boundaries

In a world filled with division, suspicion, and indifference, the story of the Good Samaritan remains one of the most powerful teachings ever told by Jesus.

My new song, “The Good Samaritan,” is inspired by the parable found in Luke 10:25–37, a story that challenges us to move beyond words and show mercy through action.

The Story Behind the Song

Jesus told the story of a man traveling from Jerusalem to Jericho who was attacked by robbers, beaten, and left half dead on the roadside.

Several religious men passed by him.
They saw the wounded man.
But they kept walking.

Then came a Samaritan, someone considered an outsider and enemy by the Jews of that time. Instead of ignoring the wounded stranger, he stopped, cared for his wounds, carried him to safety, and paid for his recovery.

Jesus ended the parable with a simple but life-changing command:

“Go and do likewise.”

That message became the heartbeat of this song.

Why This Message Matters Today

It is easy to talk about faith.
It is harder to live it.

The Good Samaritan reminds us that love is not measured by religious appearance, but by compassion in action. True faith bends down to help the hurting, even when it is inconvenient.

In today’s world, many people feel wounded:

  • emotionally
  • spiritually
  • financially
  • relationally

Sometimes the greatest ministry is simply stopping to care.

This song is a reminder that kindness still matters, mercy still heals, and God can use ordinary people to reflect His love.

Writing the Song

While writing The Good Samaritan, I wanted the lyrics to feel both biblical and personal, faithful to the Gospel narrative while speaking to modern listeners.

The song moves through:

  • the loneliness of the wounded traveler,
  • the silence of those who passed by,
  • and the unexpected compassion of the Samaritan.

Musically, I wanted it to carry both tenderness and hope, because mercy changes lives.

The Spiritual Challenge

The question behind the parable is not:
“Who is my neighbor?”

The real question is:
“Will I become a neighbor to someone in need?”

That is the challenge Jesus leaves with every believer.

Listen and Share

I pray this song encourages you to live out your faith with compassion, courage, and generosity.

If the song blesses you, please listen, share it with others, and help spread the message of God’s love through music.

The Importance of Church Fellowship

Not Forsaking the Gathering

Scripture

Not forsaking our own assembling together, as the custom of some is, but exhorting one another, and so much the more as you see the Day approaching. Hebrews 10:25

Reflection

With everything going on in your hectic life, it’s super easy for going to church to feel like just another thing you have to tick off in your to-do list. Almost like it’s more of a chore than something you really need to do. But really, “assembling together” is more than just showing up in a church service on Sunday. It’s about forming a genuine spiritual bond and lifting each other up in faith. “Exhorting” really just means encouraging each other in the faith and strength as you deal with all the tough stuff life brings your way.

When you choose to show up at church, it’s not just about listening to the sermon. Your being there really lifts up others and shows them you are together with them. It’s just a sweet reminder that you don’t have to face your struggles all on your own. The God you trust is so much greater than any challenges or difficulties you might encounter in your life.

No matter how tough the situation may seem, remember that His power and love far outweigh any trials you face. His strength can help you overcome obstacles that appear insurmountable. Trusting in Him provides you with the assurance that you are never alone in facing the tough stuff.

Church gatherings serve as a vital form of fellowship among believers. In the Christian faith, it’s really important to get involved in worship, connect with others through fellowship, grow spiritually by praying, learning, and sharing the Gospel through evangelism.

No one can really go it alone, and that’s why having a solid community and good connections is so important. You definitely need the steady support of your church friends to really grow in your spiritual journey. Just like iron sharpens iron, like I mentioned in an earlier lesson, the connections you build in the church can really boost your faith and help us grow in maturity.

When you come together in fellowship, you get support, stay accountable, and find strength in numbers. These things are super important for your well-being and help you grow spiritually. Ultimately, being part of a church community enriches your life and helps you stay in the right path.

Meditation

Togetherness.

When you think about the word “together,” it really brings to mind a strong feeling of connection and the cool experiences we share that make us feel closer. It shows how coming together builds strength through friendship and support, helping you face both happy and challenging times with others. This idea highlights how your life is enriched by collaboration and companionship. You will find greater meaning in life when you share it with others.

“Together” is such a heartfelt reminder of how important relationships are and the support you get from being in a community. It’s comforting to realize that you’ll always have a seat at God’s table, and this is such a warm thought. It really shows that you belong and people care about you and support you. You have a special place in God’s family of believers.

When you feel united and have a common goal, it really helps you connect with others on a deeper level. It strengthens your relationships and lifts up your spirit. In the end, the idea of being together shows how believing in God and having strong bonds with others can really make life feel rich and fulfilling.

It highlights how crucial it is to create and take care of relationships that lift you up and help you out, building a community vibe that makes everyone feel better. This shared vibe helps you remember you are not on this journey by yourself. When you share your experiences and support others, you will find meaning and happiness in life. Togetherness is therefore not just a concept, but a valuable practice that profoundly shapes your existence.

Having this kind of confidence can turn into a powerful strength, giving you the courage to deal with whatever life throws at you. Just remember, you’re not alone in your challenges, and there’s always

A Spiritual Reflection on the Body of Christ

A glowing human figure composed of interconnected light strands walks through a vibrant cosmic space.

The Body of Christ

Scripture

For as the body is one and has many members, and all the members of the body, being many, are one body; so also is Christ. 1 Corinthians 12:12.

Reflection

Think about all the different parts that make up your body. An eye does a totally different job than a foot, but both are super important for how the body works as a whole. It’s kind of the same when you join a church. You’re not just joining a group. You’re becoming an important part of a living, breathing entity.

Every person brings their own views, experiences, and heart that can’t be replaced. So don’t stress about fitting in with everyone else in the pews. Your uniqueness is what makes you valuable. Everyone is linked by the same Holy Spirit, and it’s super important that you lean on others to really know what God’s love is all about.

If the hand decided to say to the feet that they don’t really matter, the whole body would really struggle to function properly. Just imagine if the eye went around saying it was more valuable than the ears; the whole body would still struggle to function properly. It’s clear that every single part of the body is integral, relying on one another for optimal performance and health. Ultimately, this interdependence highlights how teamwork among all body parts is essential for proper operation.

Every believer has a special role in the body of Christ, bringing their own gifts and talents to the table, and everyone’s contribution matters in the bigger picture of the church. Every single person in the body, no matter what they’re up to, helps build that feeling of togetherness and purpose.

Christ is the head of the church, which is also called the body of Christ. Just like your brain tells your body how to move, Christ is the one who guides and leads the church. The church works together as one big team under His direction, so His role is super important to your faith. In a nutshell, Christ is a big part of who the church is and what it’s meant to do.

To say it differently, 1 Peter 2:4-6 explains that Christ is the living cornerstone, (head) and believers are the living stones (parts) that come together to build God’s Holy temple (Church or body of Christ).

Life Application

So this week, I want to challenge you to spend some time just looking around and thinking about how you can make a difference! Try and find a cool way to help someone out or give them a little boost in your church or community. Just keep in mind that even little gestures, like a smile or a helping hand, can greatly touch someone else’s life, creating waves of kindness that go far beyond the moment.

Why not think about giving someone a hand if you know they’re going through a tough time? Just a little kindness can go a long way in bringing you closer to your community. This is a great opportunity to really connect with others. Caring for others is really important, and it can show up in so many ways, especially when someone’s having a good time or going through tough stuff.

When it comes to celebrating successes or being there for someone when things get tough, getting together to lift each other up really says a lot. Doing little random acts of kindness and being thoughtful can really make a difference. They help spread good vibes in your own life and throughout the community. By embodying this spirit, you can foster a culture of compassion that benefits everyone involved.

A Lamp for your path

Devotion

 

Scripture

 

Your word is a lamp to my feet, and a light for my path. Psalm 119:105

 

 

Reflection

 

Have you ever walked down a dark road with just a tiny flashlight? It just lights up a small area around you, doesn’t it? It doesn’t really show you the whole forest out there.

 

It just shows you the next couple of steps in front of you. This feels a lot like how God uses the Bible in your life. You often want that big spotlight that shows you your whole future, but what God gives you is more like a little lamp, helping you take one step at a time.

 

When you’re diving into the Bible, don’t get too down if some parts feel confusing or hard to grasp. Try to focus on the “light” around you, like the love you feel, the hope for peace, and those small hints of His ongoing kindness.

 

When you decide to go with the light you have and take that next step, you’ll start to see that the road ahead gets clearer as you keep following His lead.

 

Jesus is the light for the whole world. When you follow Him, you will walk in His light. This is what John 8:12 tells you.

 

Thought-Provoking Question

 

Is there a particular “next step” in your life right now that strongly calls for the guiding light of God’s presence?

 

Maybe you’re looking for a specific Bible verse that can give you some comfort and clarity while dealing with whatever challenge you’re facing right now.

 

Look for scripture verses that really resonate with you; reflecting on them can help you find some peace when things are getting tough.

 

Just take a little time to read through John 1:5 and 2 Corinthians 4:6. They reveal some really important perspectives on Jesus as the light of eternal life.

 

Each of these verses provides valuable wisdom that can enhance your understanding and perspective. I encourage you to reflect on their meanings and how they apply to your life journey.

Feast of Tabernacle: devotion

Devotion

photo of a river

Prayer

Heavenly Father, we pray for soft, responsive, and receptive hearts to hear You speak to us. We pray for the transformation of our hearts and minds, in Jesus’ name, Amen.

Setting

Jesus left Judea and came to Galilee because the Jewish religious rulers were plotting to harm Him. The Israelites were celebrating the feast of Tabernacles for 8 days. This feast commemorates the 40 years of wilderness wandering. The highlight of the feast was the water ceremony on the last day.

John 7:37-39

Now on the last and greatest day of the feast, Jesus stood and cried out, “If anyone is thirsty, let him come to me and drink! He who believes in me, as the Scripture has said, from within him will flow rivers of living water.” But he said this about the Spirit, which those believing in him were to receive. For the Holy Spirit was not yet given, because Jesus wasn’t yet glorified.

Reflection

The priest performed the water ceremony on the last day of the feast of Tabernacle. The priest will take water from the pool of Siloam with a golden pitcher, walk around the altar 7 times, and pour the water on the altar. Just when the priest was pouring out the water, Jesus declared in a loud voice, “Let anyone who is thirsty come to me and drink. Who ever believes in me, as Scripture has said, rivers of living water will flow from within them.” The Holy Spirit is symbolically represented by living water. Jesus is symbolized by the rock. The water ceremony was a profound way to remember the story in Exodus 17:6. “Behold, I will stand before you there on the rock in Horeb, and you shall strike the rock, and water will come out of it, that the people may drink. And Moses did so in the sight of the elders of Israel.” 

Application

The promise of salvation is a universal promise. If you come to Jesus and receive Him as your Lord and Saviour, you will be saved, and the Holy Spirit will enter into you. To be saved, one must accept Jesus’ invitation with a positive response and believe in Him. The joy of the Holy Spirit will overflow from within you to others. 

Matthew 11:28, “Come to Me, all you who labor and are heavy laden, and I will give you rest.”

Prayer

Dear God, we believe that Jesus of Nazareth is the Messiah and the Holy One of Israel. Thank You for salvation, justification, sanctification and eternal life. Thank You for mercy and grace, in Jesus name, we pray. Amen.

Devotion: false prophets

Devotion

Setting

In Matthew 7:12- 14, Jesus gave us the golden rule: do to others what you want others to do to us and be kind to others if you want others to be kind to us. Jesus explained that He is the only way to God and the gate to salvation. After this, He warned us against false prophets.

Matthew 7:15-20

Beware of false prophets, who come to you in sheep’s clothing, but inwardly are ravening wolves. By their fruits you will know them. Do you gather grapes from thorns or figs from thistles? Even so, every good tree produces good fruit, but the corrupt tree produces evil fruit. A good tree can’t produce evil fruit, neither can a corrupt tree produce good fruit. Every tree that doesn’t grow good fruit is cut down and thrown into the fire. Therefore, by their fruits you will know them.

Reflection

Jesus warned us to watch out for false prophets who peddle false doctrines to lead people astray. They masquerade as sheep in wolf’s clothing to deceive people with heretic teachings. They misused the gospel for personal enrichment and financial gains. False prophets were plentiful in the first-century world and even today.

We can detect false teachers by inspecting their fruits. A good tree produces good fruit. A bad tree produces bad fruit. Examine every teacher for the fruit of the spirits. Genuine teachers will have the fruit of the Spirit.

Galatians 5:22-23: But the fruit of the Spirit is love, joy, peace, patience, kindness, goodness, faith, gentleness, and self-control. Against such things, there is no law.

Application

This passage is very relevant to us today because there are so many false teachers today masquerading as sheep among wolves. 

Do not believe everything you hear or read. Countercheck everything you hear or read with the scriptures. Learn the Bible and be biblically literate. This is the best safeguard against heresy. 

Prayer

Heavenly Father, we pray for the revelation of truth. We pray for the nourishment and strengthening of our souls. We pray for maturity in faith, in Jesus’ name, Amen.

Do not judge: devotion

Dr. Andrew C S Koh

photo of an open bible
open bible

Setting

Matthew 7 is a continuation of Jesus’ sermon on the Mount where Jesus taught on judging others, spiritual discernment, relationship, and wisdom.

Matthew 7:1-5

1 Don’t judge, so that you won’t be judged. 2 For with whatever judgment you judge, you will be judged; and with whatever measure you measure, it will be measured to you. 3 Why do you see the speck that is in your brother’s eye, but don’t consider the beam that is in your own eye? 4 Or how will you tell your brother, ‘Let me remove the speck from your eye,’ and behold, the beam is in your own eye? 5 You hypocrite! First,  remove the beam out of your own eye, and then you can see clearly to remove the speck out of your brother’s eye.

Reflection

We cannot judge other people because we are sinners under God’s judgment, Romans 3:22. If we judge we are like pots calling kettles black. We cannot judge others righteously because we are not righteous. Judging others will only bring judgment to ourselves because God will judge us.

Jesus asked two rhetorical questions. These are questions to emphasize a point and do not require any answers.

Why are we so fast to see a speck of sawdust in other people’s eye but could not see the log of wood in our own eyes?   How are we going to remove the speck of sawdust in other people’s eye when our vision is blocked by a log in our own eyes? 

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

Application

There are practical instructions to obey and apply.

Do not be a hypocrite. Remove the log in your own eye first before attempting to remove the speck of sawdust in other people’s eyes. Examine yourself first. Are you perfect? Are you qualified to judge? 

Confess, repent, and ask God to forgive your sins. Claim the promise of 1 John 1:9.

Do not take the law into your own hands. Let God be the judge, instead of judging others. Forgive others as God has forgiven you. Do not take vengeance on others. Let God deal with it.

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

Prayer

Heavenly Father, help us not to be judgmental and self-righteous. Thank You for reminding us that we are sinners under Your judgment. Thank You for redemption, reconciliation, justification, sanctification, salvation and eternal life, in Jesus’ name, Amen.
