John 1:7

In context

5The light shines on in the darkness, and the darkness did not take hold of it. 6A man appeared, sent from God; his name was John. 7He came as a witness, to testify about the light, so that through him everyone might believe. 8He himself was not the light; he came to testify about the light. 9The true light, which gives light to every human being, was coming into the world.
