Whoever is born of God, does not sin  -  1 John 5:18

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.

John stated the fact that the one who has the divine nature doesn’t practice sin. This does not mean that they are sinless but when they sin, they are sensitive to it and do all they can to avoid it becoming a part of their lives.
