“This passage is exceedingly adapted to point out the power and nature of faith; that it is a certainty, relying on the goodness of God, which does not admit of doubt. For Christ does not acknowledge as believers any but those who are fully convinced that God is reconciled to them, and do not doubt that he will give what they ask.”
