Human life, then, we may see as the preparing for the life of Heaven. It means, on the one hand, complete self-conquest. The soul must conquer the body and bring it into full obedience to God’s law; and the soul must itself come into full submission to God. It has, from God’s Church, the truths it needs to know about God and man and its own destiny: from the same source it has the law that will govern it in the right use of itself and in the right relation of love and duty to others. But, as has been seen, given that man is to live a life above his nature, he needs those gifts above his nature which we call the Supernatural Life.
