27 But how could he be? For we know where this man comes from. When the Messiah comes, he will simply appear; no one will know where he comes from." 28 While Jesus was teaching in the Temple, he called out, "Yes, you know me, and you know where I come from. But I'm not here on my own. The one who sent me is true, and you don't know him. 29 But I know him because I come from him, and he sent me to you." 30 Then the leaders tried to arrest him; but no one laid a hand on him, because his time had not yet come. 31 Many among the crowds at the Temple believed in him. "After all," they said, "would you expect the Messiah to do more miraculous signs than this man has done?"

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.
