But let no one ever speak to you of “blind” belief. Faith opens your eyes; it does not close them. Faith gives vision; and without vision men die, for they become nothing more than cattle. Faith is that gift of God which allows you to see through appearances and to focus on substance; it is that special God-given grant which gives you evidence of things that cannot be seen. That is exactly how God the Holy Spirit once described faith through this same St. Paul. “It is the substance of things to be hoped for,” He said, “the evidence of things that are not seen.” (Hebrews 11:1) Faith is a gift and a grant that defies evaluation, for it enables you to see beyond that last horizon where burning sand and flaming sky blur into one and to rest your eyes on the only Oasis where exiled man will find the water that will let him live. It is no mirage. It will never induce desert madness: for it is God.
