Ephesians, Lesson 17

Lesson 17

Ephesians 6:10-13, spiritual warfare, part 1.

V 10, Finally, my brethren, be strong in the Lord and in the power of His might.

Paul encouraged his listeners, (and us) to stand firm in the Lord in the power of His might, not ours. We are weak but He is strong, and our weakness is perfected in His strength.

2 Corinthians 12:19 a, “My grace is sufficient for you, for My strength is made perfect in weakness.”

V 11, Put on the whole armor of God, that you may be able to stand against the wiles of the devil.

God provided us with spiritual armor. We are to wear this armor to defend and attack against the demonic onslaught. These are the spiritual weapons to fight spiritual warfare.

2 Cor 10:4-5, “For the weapons of our warfare are not carnal but mighty in God for pulling down strongholds, casting down arguments and every high thing that exalts itself against the knowledge of God, bringing every thought into captivity to the obedience of Christ”.

VV 12-13, 12 For we do not wrestle against flesh and blood, but against principalities, against powers, against the rulers of the darkness of this age, against spiritual hosts of wickedness in the heavenly places. 13 Therefore take up the whole armor of God, that you may be able to withstand in the evil day, and having done all, to stand.

Our battle is not physical but spiritual. Our battle is against the hierarchy of satanic demons called the principalities and powers, the rulers of darkness, and the spiritual wickedness in high places. Paul commanded his audience (and us), to wear the whole armor of God and stand firm in the faith. We must win the battle in the spiritual realm before we can see a breakthrough in the physical realm.
