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. 31 Many from the crowd committed themselves in faith to him, saying, "Will the Messiah, when he comes, provide better or more convincing evidence than this?"

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.
Commentary on John 7:31-36
(Read John 7:31-36)
The discourses of Jesus convinced many that he was the Messiah; but they had not courage to own it. It is comfort to those who are in the world, but not of it, and therefore are hated by it and weary of it, that they shall not be in it always, that they shall not be in it long. Our days being evil, it is well they are few. The days of life and of grace do not last long; and sinners, when in misery, will be glad of the help they now despise. Men dispute about such sayings, but the event will explain them.
