There was a man sent from God, whose name was John. He came as a witness, to bear witness about the light, that all might believe through him. He was not the light, but came to bear witness about the light (John 1:6-8).
It is interesting how the apostle John interjects this short snippet on John the Baptist into the theology of Christ, especially when he gives a fuller account of John’s ministry in the latter part of the chapter. What is its purpose? Why here, why at this point?
The point can be gathered, I believe, by looking at the verbal emphasis of these few verses. Of John the Baptist, the apostle writes, “[John] came as a witness, to bear witness about the Light … [John] was not the Light, but he came to bear witness about the Light.” The term “witness” is used three times, whether in its noun or verb form, and it is an important part of the apostle’s discourse.
