Q. 21 What is true faith?
A.  True faith is not only a knowledge and conviction that everything that God reveals in his Word is true; it is also a deep-rooted assurance, created in me by the Holy Spirit through the gospel, that, out f sheer grace earned for us by Christ, not only others, but I too have had my sins forgiven, have been made forever right with God, and have been granted salvation.
