John Calvin: What is Faith?
Commenting on Romans 4:14:
“Faith then is not a naked knowledge either of God or of his truth; nor is it a simple persuasion that God is, that his word is the truth; but a sure knowledge of God’s mercy, which is received from the gospel, and brings peace of conscience with regard to God, and rest to the mind. The sum of the matter then is this — that if salvation depends on the keeping of the law, the soul can entertain no confidence respecting it, yea, that all the promises offered to us by God will become void: we must thus become wretched and lost, if we are sent back to works to find out the cause or the certainty of salvation.”
