“…I have written unto you, young men, because ye are strong, and the word of God abideth in you, and ye have overcome the wicked one.” 1 John 2:14
Make no mistakes about it; there is a wicked one and he is your adversary, busying about seeking your destruction:
“Be sober, be vigilant; because your adversary the devil, as a roaring lion, walketh about, seeking whom he may devour:” 1 Peter 5:8
But there is nothing to fear, the one in you is greater than the one in world:
“Ye are of God, little children, and have overcome them: because greater is he that is in you, than he that is in the world.” 1 John 4:4
The Spirit that dwells in you is the Spirit of the living God- not the spirit of the world- and he is greater than all.
“Now we have received, not the spirit of the world, but the spirit which is of God…” 1 Corinthians 2:12
“…And hereby we know that he abideth in us, by the Spirit which he hath given us.” 1 John 3:24
So he says:
“Whom resist stedfast in the faith, knowing that the same afflictions are accomplished in your brethren that are in the world.” 1 Peter 5:9
Resist the wicked one, remaining steadfast in the faith; steadfast in the word. No matter what he throws at you, as long as the word abides in you and is expressed by your strong faith, you would quench all his fiery darts- you have overcome!
