But it is a mystery of God's providence, not of the existence of evil as such. God could, if He wished, give us the full explanation of His dealings with mankind. But He has not seen fit to do so. Because He does not reveal everything about Himself is no reason why we should not be grateful for what He does reveal. All these and other truths, not acquirable by human study, faith teaches us.
Faith thus gives the solution to the problem of life.
It tells us that we have not here a lasting city but that we seek one which is to come. It proclaims that this life is not solely enjoyment but probation, and that this world is not the goal but starting point of man. Not to mention other truths of faith, what we have enumerated show us the great value of faith. It explains life, which is otherwise a despairing problem. It gives a motive for patiently bearing the vicissitudes of life, which otherwise might crush us.
