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) 8} The one who does what is sinful is of the devil,^(T) because the devil has been sinning from the beginning. The reason the Son of God^(U) appeared was to destroy the devil’s work.^{(V) 9} No one who is born of God^(W) will continue to sin,^(X) because God’s seed^(Y) remains in them; they cannot go on sinning, because they have been born of God. ¹⁰ This is how we know who the children of God^(Z) are and who the children of the devil^(AA) are: Anyone who does not do what is right is not God’s child, nor is anyone who does not love^(AB) their brother and sister.^(AC)
