2 Cor 4:4, 1 Jn 3:8, James 4:7, Eph 4:27, Eph 6:11
The devil deceives us so that we don't realize that Jesus is the Christ. (2 Cor 4:4)
2 Cor 4:4 In whom the god of this world hath blinded the minds of them which believe not, lest the light of the glorious gospel of Christ, who is the image of God, should shine unto them.
Jesus came to this earth and destroyed the works of the devil. (1Jn 3:8)
He that committeth sin is of the devil; for the devil sinneth from the beginning. For this purpose the Son of God was manifested, that he might destroy the works of the devil.
Therefore, we must resist the devil so that he cannot take advantage of it. (1Pt 5:8-9, James 4:7, Eph 6:11)
1Pt 5:8 Be sober, be vigilant; because your adversary the devil, as a roaring lion, walketh about, seeking whom he may devour: 9 Whom resist stedfast in the faith, knowing that the same afflictions are accomplished in your brethren that are in the world.
James 4:7 Submit yourselves therefore to God. Resist the devil, and he will flee from you.
Eph 6:11 Submit yourselves therefore to God. Resist the devil, and he will flee from you.
