Acts 3:8

"And immediately his feet and ankle bones received strength. And he leaping up stood, and walked." Perhaps it was by way of trying himself that he put it thus to further proof, whether perchance the thing done might not be to no purpose. His feet were weak; it was not that he had lost them. Some say that he did not even know how to walk. "And entered with them into the temple." Of a truth it was marvellous. The Apostles do not urge him; but of his own accord he follows, by the act of following pointing out his benefactors. "And leaping and praising God;" not admiring them, but God that wrought by them. The man was grateful.

And the wonder is, that he believed so readily. For those who are set free from diseases of long standing, hardly believe their very eyesight. Once healed, he remains with the Apostles, giving thanks to God. "And he entered," it is said, "with them into the temple, walking, and leaping, and praising God." Observe how restless he is, in the eagerness of his delight, at the same time shutting the mouths of the Jews. Also, that he leaped, was to prevent the suspicion of hypocrisy; for after all, this was beyond the possibility of deception. For if previously he was totally unable to walk, even when hunger pressed hard (and indeed he would not have chosen to share with his bearers the proceeds of his begging, if he had been able to manage for himself), this holds still more in the present case. And how should he have feigned in behalf of those who had given him no alms? But the man was grateful, even after his recovery. And thus on either side his faith is shown, both by his thankfulness, and by the recent event.
