1 John 3:1–3
3 See what kind of love the Father has given to us, that we should be called children of God; and so we are. The reason why the world does not know us is that it did not know him. 2 Beloved, we are God’s children now, and what we will be has not yet appeared; but we know that when he appears[a] we shall be like him, because we shall see him as he is. 3 And everyone who thus hopes in him purifies himself as he is pure.
