25 That's when some of the people of Jerusalem said, "Isn't this the one they were out to kill? 26 And here he is out in the open, saying whatever he pleases, and no one is stopping him. Could it be that the rulers know that he is, in fact, the Messiah? 27 And yet we know where this man came from. The Messiah is going to come out of nowhere. Nobody is going to know where he comes from." 28 That provoked Jesus, who was teaching in the Temple, to cry out, "Yes, you think you know me and where I'm from, but that's not where I'm from. I didn't set myself up in business. My true origin is in the One who sent me, and you don't know him at all. 29 I come from him - that's how I know him. He sent me here." 30 They were looking for a way to arrest him, but not a hand was laid on him because it wasn't yet God's time.

Commentary on John 7:25-30
(Read John 7:25-30)
Christ proclaimed aloud, that they were in error in their thoughts about his origin. He was sent of God, who showed himself true to his promises. This declaration, that they knew not God, with his claim to peculiar knowledge, provoked the hearers; and they sought to take him, but God can tie men's hands, though he does not turn their hearts.
