Thus you see how rich a Christian is, that is, one who has been baptized! Even if he would, he could not lose his salvation, however much he sinned, unless he refused to believe. For no sin can condemn him save unbelief alone. All other sins, so long as the faith in God’s promise made in baptism returns or remains, are immediately blotted out through that same faith, or rather through the truth of God, because he cannot deny himself if you confess him and faithfully cling to him in his promise. But as for contrition, confession of sins, and satisfaction, along with all those carefully devised exercises of men: if you rely on them and neglect this truth of God, they will suddenly fail you and leave you more wretched than before. For whatever is done without faith in God’s truth is vanity of vanities and vexation of spirit.
