1 John
King James Version (KJV)

“We know that whosoever is born of God sinneth not; but he that is begotten of God keepeth himself, and that wicked one toucheth him not.”
King James Version (KJV)
5:18 Yet this gives us no encouragement to sin: on the contrary, it is an indisputable truth, he that is born of God - That sees and loves God. Sinneth not - So long as that loving faith abides in him, he neither speaks nor does anything which God hath forbidden. He keepeth himself - Watching unto prayer. And, while he does this, the wicked one toucheth him not - So as to hurt him.
1Jo 5:18 Whosoever is born of God sinneth not. Does not live a life of sin. He will not sin unto death, though he may be overtaken in a fault. See PNT "1Joh 5:21". That wicked one toucheth him not. Cannot lay hands on him so as to hold him.
