1 John 3:1-7 CEB

1 See what kind of love the Father has given to us in that we should be called God's children, and that is what we are! Because the world didn't recognize him, it doesn't recognize us.
2 Dear friends, now we are God's children, and it hasn't yet appeared what we will be. We know that when he appears we will be like him because we'll see him as he is.
3 And everyone who has this hope in him purifies himself even as he is pure.
4 Every person who practices sin commits an act of rebellion, and sin is rebellion.
5 You know that he appeared to take away sins, and there is no sin in him.
6 Every person who remains in relationship to him does not sin. Any person who sins has not seen him or known him.

Practicing sin or righteousness

7 Little children, make sure no one deceives you. The person who practices righteousness is righteous, in the same way that Jesus is righteous.
