1 John 3:7-10

Generally
speaking, it is easy to know the difference between what is right and
wrong. Sometimes, though, we do have doubts. I wonder why, then, do we
find ourselves so often in a state of sin rather than in a state of
grace? It seems that we often choose the wrong course of action.

7 Children, let no one deceive you. The person who acts in righteousness is righteous, just as he is righteous. 8 Whoever
sins belongs to the devil, because the devil has sinned from the
beginning. Indeed, the Son of God was revealed to destroy the works of
the devil. 9 No one who is begotten by God commits sin,
because God’s seed remains in him; he cannot sin because he is begotten by God. 10 In
this way, the children of God and the children of the devil are made
plain; no one who fails to act in righteousness belongs to God, nor
anyone who does not love his brother.
