Luke 5:12

Luke 5:12. And it came to pass, when he was in a certain city, behold a man full of leprosy: who seeing Jesus fell on his face, and besought him, saying, Lord, if thou wilt, thou canst make me clean.

There was not much faith there, but faith even as a grain of mustard seed will serve; and therefore Christ did not refuse the poor leper’s plea.
