It follows, but the just shall live by his faith. The Prophet, I have no doubt, does here place faith in opposition to all those defences by which men so blind themselves as to neglect God, and to seek no aid from him. As men therefore rely on what the earth affords, depending on their fallacious supports, the Prophet here ascribes life to faith. But faith, as it is well known, and as we shall presently show more at large, depends on God alone. That we may then live by faith, the Prophet intimates that we must willingly give up all those defences which are wont to disappoint us. He then who finds that he is deprived of all protections, will live by his faith, provided he seeks in God alone what he wants, and leaving the world, fixes his mind on heaven.
