1 John 3: 1 - 3
1 See what love the Father has given 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; it does not yet appear what we shall be, but we know that when he appears we shall be like him, for we shall see him as he is.
3 And every one who thus hopes in him purifies himself as he is pure.
