NECESSITY OF THE VIRTUE OF HOPE
The Prince of the Apostles has left us an admonition urging us to render an account not only of our faith, but also of the hope that is in us. In the first part of the present work we have briefly set forth the teaching of Christian faith. We now turn to the task of undertaking, in compendious fashion, an exposition of the truths pertaining to hope.
We should recall that in one kind of knowledge, man's desire can come to rest. We naturally desire to know truth, and when we do know it, our craving in this direction is satisfied. But in the knowledge of faith man's desire never comes to rest. For faith is imperfect knowledge: the truths we accept on faith are not seen. This is why the Apostle calls faith "the evidence of things that appear not" (Heb. 11:1).
Accordingly, even when we have faith, there still remains in the soul an impulse toward something else, namely, the perfect vision of the truth assented to on faith, and the attainment of whatever can lead to such truth. As we pointed out above, among the various teachings of faith there is one according to which we believe that God exercises providence over human affairs. In consequence of this belief, stirrings of hope arise in the soul of the believer that by God's help he may gain possession of the goods he naturally desires, once he learns of them through faith. Therefore, as we mentioned at the very beginning, next after faith, the virtue of hope is necessary for the perfection of Christian living.
