19 But deliver us from evil.

20 What does this mean? — Answer. We pray in this petition, as in a summary, that our Father in heaven would deliver us from all manner of evil, of body and soul, property and honor, and at last, when our last hour shall come, grant us a blessed end, and graciously take us from this vale of tears to Himself into heaven.

21 Amen. What does this mean? — Answer. That I should be certain that these petitions are acceptable to our Father in heaven and heard; for He Himself has commanded us so to pray, and has promised that He will hear us. Amen, Amen; that is, Yea, yea, it shall be so.
