The next step of Abraham's faith was this, he casteth himself and flingeth his soul, as I may say, upon the all-sufficient power and mercy of God for the attainment of what he desireth; he rolleth and tumbleth himself, as it were, upon the all-sufficiency of God. This you shall find in Rom. iv. 18, where the apostle, speaks of Abraham, who "against hope, believed in hope"; that is, when there was no hope in the world, yet he believed in God, even above hope, and so made it possible. It was an object of his hope, that it might be in regard of God, howsoever there was no possibility in regard of man. So the text saith, "he considered not his own body now dead, when he was about a hundred years old, neither yet the deadness of Sarah's womb, but was strong in faith." He cast himself wholly upon the precious promise and mercy of God.
