Isaiah 33:24

And the inhabitant shall not say, I am sick, not one of them shall be subject to illness or weakness; the people that dwell therein shall be forgiven their iniquity, this, in fact, being the secret of their strength. And thus the Church of God is constituted it consists of people who have come to the full realization of their own helplessness, who are deeply repentant, and who, as a consequence, have received the gift of the forgiveness of their sins and draw upon the Lord alone for all their strength. That is the abiding comfort of all believers.
