³ Now by this we may be sure that we know him, if we obey his commandments. ⁴ Whoever says, ‘I have come to know him’, but does not obey his commandments, is a liar, and in such a person the truth does not exist; ⁵ but whoever obeys his word, truly in this person the love of God has reached perfection. By this we may be sure that we are in him: ⁶ whoever says, ‘I abide in him’, ought to walk just as he walked.

A New Commandment

⁷ Beloved, I am writing you no new commandment, but an old commandment that you have had from the beginning; the old commandment is the word that you have heard. ⁸ Yet I am writing you a new commandment that is true in him and in you, because^[a] the darkness is passing away and the true light is already shining. ⁹ Whoever says, ‘I am in the light’, while hating a brother or sister,^[b] is still in the darkness. ¹⁰ Whoever loves a brother or sister^[c] lives in the light, and in such a person^[d] there is no cause for stumbling. ¹¹ But whoever hates another believer^[e] is in the darkness, walks in the darkness, and does not know the way to go, because the darkness has brought on blindness.

The Word Became Flesh

1 In the beginning was the Word, and the Word was with God, and the Word was God. ² He was in the beginning with God. ³ All things came into being through him, and without him not one thing came into being. What has come into being ⁴ in him was life,^[a] and the life was the light of all people. ⁵ The light shines in the darkness, and the darkness did not overcome it.

⁶ There was a man sent from God, whose name was John. ⁷ He came as a witness to testify to the light, so that all might believe through him. ⁸ He himself was not the light, but he came to testify to the light. ⁹ The true light, which enlightens everyone, was coming into the world.^[b]

¹⁰ He was in the world, and the world came into being through him; yet the world did not know him. ¹¹ He came to what was his own,^[c] and his own people did not accept him. ¹² But to all who received him, who believed in his name, he gave power to become children of God, ¹³ who were born, not of blood or of the will of the flesh or of the will of man, but of God.

¹⁴ And the Word became flesh and lived among us, and we have seen his glory, the glory as of a father’s only son,^[d] full of grace and truth. ¹⁵ (John testified to him and cried out, ‘This was he of whom I said, “He who comes after me ranks ahead of me because he was before me.”’) ¹⁶ From his fullness we have all received, grace upon grace. ¹⁷ The law indeed was given through Moses; grace and truth came through Jesus Christ. ¹⁸ No one has ever seen God. It is God the only Son,^[e] who is close to the Father’s heart,^[f] who has made him known.
