God wishes for us to pray to Him for all the things that affect our bodily interests, so that we seek and expect help nowhere else except in Him. But He has put this matter last. For if we are to be preserved and delivered from all evil, God's name must first be hallowed in us, His kingdom must be with us, and His will must be done. After that He will finally preserve us from sin and shame, and, besides, from everything that may hurt or harm us.
So God has briefly placed before us all the distress that may ever come upon us, so that we might have no excuse whatever for not praying. But all depends upon this, that we learn also to say "Amen." This means that we do not doubt that our prayer is surely heard and that what we pray shall be done. This is nothing else than the word of undoubting faith, which does not pray on a dare but knows that God does not lie to him. For He has promised to grant it. Therefore, where there is no such faith, there cannot be true prayer either.
It is, therefore, an evil deception on those who pray as though they could not dare from the heart to say "Yes!" and positively conclude that God hears them. Instead, they remain in doubt and say, "How can I be so bold as to boast that God hears my prayer? For I am but a poor sinner." The reason for this is, they do not respect God's promise, but they rely on their own worthiness… (paragraphs 117-122)
