The reason the world does not know us is that it did not know him.^{(C) 2} Dear friends,^(D) now we are children of God,^(E) and what we will be has not yet been made known. But we know that when Christ appears,^[a](F) we shall be like him,^(G) for we shall see him as he is.^{(H) 3} All who have this hope in him purify themselves,^(I) just as he is pure.^(J)
