Luke 5:25

‘And immediately he rose up before them, and took up that on which he lay, and departed to his house, glorifying God.'

And he did just that. He rose, took up what he was lying on, and went home glorifying God. So having accomplished the harder, Jesus had the right to expect that they would agree about the easier, or at least think about it.

But it is one of the evidences of the hardness of men's hearts that once they have determined something, they regularly stick to it, however much they might be proved to be wrong. It is in the end the test of the open or closed mind. And the minds of these men were firmly closed. There was no excuse for them. They had asked for proof and they had received it. But it was not really proof that they wanted, but submission to their ideas. Here was one who had made the paralytic walk when they could not. What did it tell the world? It told it that He was from God. But that they could not stomach. Let us not think of these men as sincerely wrong. They had proved themselves totally insincere. They did not want the truth. They only wanted to be acknowledged as right.
