Introduction^(A)

1 Many have undertaken to draw up an account of the things that have been fulfilled^[a] among us, ² just as they were handed down to us by those who from the first^(B) were eyewitnesses^(C) and servants of the word.^{(D) 3} With this in mind, since I myself have carefully investigated everything from the beginning, I too decided to write an orderly account^(E) for you, most excellent^(F) Theophilus,^{(G) 4} so that you may know the certainty of the things you have been taught.^(H)

The Incarnation of the Word of Life

1 That which was from the beginning,^(A) which we have heard, which we have seen with our eyes,^(B) which we have looked at and our hands have touched^(C)—this we proclaim concerning the Word of life. ² The life appeared;^(D) we have seen it and testify to it,^(E) and we proclaim to you the eternal life,^(F) which was with the Father and has appeared to us. ³ We proclaim to you what we have seen and heard,^(G) so that you also may have fellowship with us. And our fellowship is with the Father and with his Son, Jesus Christ.^{(H) 4} We write this^(I) to make our^[a] joy complete.^(J)

Light and Darkness, Sin and Forgiveness

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