John 7:28-32

Then Jesus, while teaching in the temple courts, cried out, “You both know me and know where I come from! And I have not come on my own initiative, but the one who sent me is true. You do not know him, but I know him, because I have come from him and he sent me.” So then they tried to seize Jesus, but no one laid a hand on him, because his time had not yet come. Yet many of the crowd believed in him and said, “Whenever the Christ comes, he won’t perform more miraculous signs than this man did, will he?” The Pharisees heard the crowd murmuring these things about Jesus, so the chief priests and the Pharisees sent officers to arrest him.

The Pharisees, over and over again, are offended at what and how Jesus speaks. In this verse it's to the point where they try to arrest him, fail, and instead of deterring people from believing in Him, many DO believe in Him. In fact, many of the ways the Pharisees attempt to trap or capture Christ fail. They fail because Jesus only does the will of the Father. Because He does exactly what He sees His Father doing - it is impossible for Him to be captured or overtaken until "His time has come". If the Pharisees were able to accept who Jesus is they would stop trying to capture Him, because whatever He does will succeed. His word has come forth and He will accomplish exactly what He desires. (Isaiah 55:11)
