Q&A 21

Q: What is true faith?

A: True faith is
not only a knowledge and conviction
that everything God reveals in his Word is true;1
it is also a deep-rooted assurance,2
created in me by the Holy Spirit3 through the gospel,4
that, out of sheer grace earned for us by Christ,5
not only others, but I too,6
have had my sins forgiven,
have been made forever right with God,
and have been granted salvation.7
