¹⁶ For God so loved^(A) the world that he gave^(B) his one and only Son,^(C) that whoever believes^(D) in him shall not perish but have eternal life.^{(E) 17} For God did not send his Son into the world^(F) to condemn the world, but to save the world through him.^{(G) 18} Whoever believes in him is not condemned,^(H) but whoever does not believe stands condemned already because they have not believed in the name of God’s one and only Son.^{(I) 19} This is the verdict: Light^(J) has come into the world, but people loved darkness instead of light because their deeds were evil.^{(K) 20} Everyone who does evil hates the light, and will not come into the light for fear that their deeds will be exposed.^{(L) 21} But whoever lives by the truth comes into the light, so that it may be seen plainly that what they have done has been done in the sight of God.

Light and Darkness, Sin and Forgiveness

⁵ This is the message we have heard^(A) from him and declare to you: God is light;^(B) in him there is no darkness at all. ⁶ If we claim to have fellowship with him and yet walk in the darkness,^(C) we lie and do not live out the truth.^{(D) 7} But if we walk in the light,^(E) as he is in the light, we have fellowship with one another, and the blood of Jesus, his Son, purifies us from all^[a] sin.^(F)

⁹ Anyone who claims to be in the light but hates a brother or sister^[a](A) is still in the darkness.^{(B) 10} Anyone who loves their brother and sister^[b] lives in the light,^(C) and there is nothing in them to make them stumble.^{(D) 11} But anyone who hates a brother or sister^(E) is in the darkness and walks around in the darkness.^(F) They do not know where they are going, because the darkness has blinded them.^(G)
