The infallible pledge of God's mercy

This is the gospel, that sins are remitted in the name of Christ; and no heart ever received tidings more glad….or when man through repentance has come to the knowledge of himself, he finds nothing but utter despair. Hence, wholly distrusting himself, he is forced to take refuge in the mercy of God. But when he has begun to do that, justice makes him afraid. Then Christ appears, who has satisfied the divine justice for our trespasses. When once there is faith in Him, then salvation is found; for He is the infallible pledge of God’s mercy.

Through Christ alone we are given salvation, blessedness, grace, pardon, and all that makes us in any way worthy in the sight of a righteous God.“

— Ulrich Zwingli (1 January 1484 – 11 October 1531, Swiss Christian theologian, musician, and leader of the Reformation in Switzerland).
