John 1:6-9

There came a man commissioned and sent from God, whose name was John. [Mal 3:1] This man came as a witness, to testify about the Light, so that all might believe [in Christ, the Light] through him. John was not the Light, but came to testify about the Light. There it was—the true Light [the genuine, perfect, steadfast Light] which, coming into the world, enlightens everyone. [Is 49:6]
