He fell upon his face, because he blushes with shame when he remembers the evils he had committed. And he is commanded to rise and walk, because he who, knowing his own weakness, lies lowly on the ground, is led to advance by the consolation of the divine word to mighty deeds. But if faith made him whole, who hurried himself back to give thanks, therefore does unbelief destroy those who have neglected to give glory to God for mercies received. Wherefore that we ought to increase our faith by humility, as it is declared in the former parable, so in this is it exemplified in the actions themselves.
