You, being in past times alienated and enemies in your mind in your evil deeds, yet now he has reconciled in the body of his flesh through death, to present you holy and without defect and blameless before him, if it is so that you continue in the faith, grounded and steadfast, and not moved away from the hope of the Good News which you heard, which was proclaimed in all creation under heaven, of which I, Paul, was made a servant. (Colossians 1:21-23)

See how great a love the Father has given to us, that we should be called children of God! For this cause the world doesn’t know us, because it didn’t know him. Beloved, now we are children of God. It is not yet revealed what we will be; but we know that when he is revealed, we will be like him, for we will see him just as he is. Everyone who has this hope set on him purifies himself, even as he is pure. Everyone who sins also commits lawlessness. Sin is lawlessness. You know that he was revealed to take away our sins, and no sin is in him. Whoever remains in him doesn’t sin. Whoever sins hasn’t seen him and doesn’t know him. Little children, let no one lead you astray. He who does righteousness is righteous, even as he is righteous. He who sins is of the devil, for the devil has been sinning from the beginning. To this end the Son of God was revealed: that he might destroy the works of the devil. Whoever is born of God doesn’t commit sin, because his seed remains in him, and he can’t sin, because he is born of God. In this the children of God are revealed, and the children of the devil. Whoever doesn’t do righteousness is not of God, neither is he who doesn’t love his brother. (1 John 3:1-10)
