Little children, you are from God and have overcome them, for he who is in you is greater than he who is in the world. (1 John 4:4)
The conflict with the devil that results from being in Christ is brutal, but the outcome is certain. He may kill us, but he cannot conquer us in the end. We rise and live forever in joy with Christ, while he is finally cast into the lake of fire. Consider two texts that show we can be killed but not utterly ruined.
They have conquered him by the blood of the Lamb and by the word of their testimony, for they loved not their lives even unto death. (Revelation 12:11)
Do not fear what you are about to suffer. Behold, the devil is about to throw some of you into prison, that you may be tested, and for ten days you will have tribulation. Be faithful unto death, and I will give you the crown of life. (Revelation 2:10)
In this battle with the devil, therefore, we are to resist him by faith and put on the armor of God. “Submit yourselves therefore to God. Resist the devil, and he will flee from you. Draw near to God, and he will draw near to you” (James 4:7–8).
“Be sober-minded; be watchful. Your adversary the devil prowls around like a roaring lion, seeking someone to devour. Resist him, firm in your faith” (1 Peter 5:8–9). “Put on the whole armor of God, that you may be able to stand against the schemes of the devil” (Ephesians 6:11).
In conclusion, weep for the helplessness of the world the way Jesus wept over Jerusalem’s blindness: “Would that you, even you, had known on this day the things that make for peace! But now they are hidden from your eyes” (Luke 19:42).
Rejoice that the providence of God is so massively active in restraining evil and prompting so much external conformity to righteousness. Trust in the triumph of Christ at Calvary. Resist the devil in faith that the one in you is greater than he. Risk your life to spread the liberating news as far as you can.
