3 See what great love^(A) the Father has lavished on us, that we should be called children of God!^(B) And that is what we are! 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)

⁴ Everyone who sins breaks the law; in fact, sin is lawlessness.^{(K) 5} But you know that he appeared so that he might take away our sins.^(L) And in him is no sin.^{(M) 6} No one who lives in him keeps on sinning.^(N) No one who continues to sin has either seen him^(O) or known him.^(P)

⁷ Dear children,^(Q) do not let anyone lead you astray.^(R) The one who does what is right is righteous, just as he is righteous.^(S)
