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)

More on Love and Hatred

¹¹ For this is the message you heard^(AD) from the beginning:^(AE) We should love one another.^{(AF) 12} Do not be like Cain, who belonged to the evil one^(AG) and murdered his brother.^(AH) And why did he murder him? Because his own actions were evil and his brother’s were righteous.^{(AI) 13} Do not be surprised, my brothers and sisters,^[b] if the world hates you.^{(AJ) 14} We know that we have passed from death to life,^(AK) because we love each other. Anyone who does not love remains in death.^{(AL) 15} Anyone who hates a brother or sister^(AM) is a murderer,^(AN) and you know that no murderer has eternal life residing in him.^(AO)

¹⁶ This is how we know what love is: Jesus Christ laid down his life for us.^(AP) And we ought to lay down our lives for our brothers and sisters.^{(AQ) 17} If anyone has material possessions and sees a brother or sister in need but has no pity on them,^(AR) how can the love of God be in that person?^{(AS) 18} Dear children,^(AT) let us not love with words or speech but with actions and in truth.^(AU)

¹⁹ This is how we know that we belong to the truth and how we set our hearts at rest in his presence: ²⁰ If our hearts condemn us, we know that God is greater than our hearts, and he knows everything. ²¹ Dear friends,^(AV) if our hearts do not condemn us, we have confidence before God^{(AW) 22} and receive from him anything we ask,^(AX) because we keep his commands^(AY) and do what pleases him.^{(AZ) 23} And this is his command: to believe^(BA) in the name of his Son, Jesus Christ,^(BB) and to love one another as he commanded us.^{(BC) 24} The one who keeps God’s commands^(BD) lives in him,^(BE) and he in them. And this is how we know that he lives in us: We know it by the Spirit he gave us.^(BF)
