1 John 3:1-10 New Revised Standard Version (NRSV)
3 1 See what love the Father has given us, that we should be called children of God; and that is what we are. The reason the world does not know us is that it did not know him. 2 Beloved, we are God’s children now; what we will be has not yet been revealed. What we do know is this: when he[a] is revealed, we will be like him, for we will see him as he is. 3 And all who have this hope in him purify themselves, just as he is pure.
4 Everyone who commits sin is guilty of lawlessness; sin is lawlessness. 5 You know that he was revealed to take away sins, and in him there is no sin. 6 No one who abides in him sins; no one who sins has either seen him or known him. 7 Little children, let no one deceive you. Everyone who does what is right is righteous, just as he is righteous. 8 Everyone who commits sin is a child of the devil; for the devil has been sinning from the beginning. The Son of God was revealed for this purpose, to destroy the works of the devil. 9 Those who have been born of God do not sin, because God’s seed abides in them;[b] they cannot sin, because they have been born of God. 10 The children of God and the children of the devil are revealed in this way: all who do not do what is right are not from God, nor are those who do not love their brothers and sisters.[c]
