VIII. Where now are they who desire to know and to do good works? Let them undertake prayer alone, and rightly exercise themselves in faith, and they will find that it is true, as the holy Fathers have said, that there is no work like prayer. Mumbling with the mouth is easy, or at least considered easy, but with earnestness of heart to follow the words in deep devotion, that is, with desire and faith, so that one earnestly desires what the words say, and not to doubt that it will be heard: that is a great deed in God's eyes. Here the evil spirit hinders men with all his powers. Oh, how often will he here prevent the desire to pray, not allow us to find time and place, nay, often also raise doubts, whether a man is worthy to ask anything of such a Majesty as God is, and so confuse us that a man himself does not know whether it is really true that he prays or not; whether it is possible that his prayer is acceptable, and other such strange thoughts. For the evil spirit knows well how powerful one man's truly believing prayer is, and how it hurts him, and how it benefits all men. Therefore he does not willingly let it happen. When so tempted, a man must indeed be wise, and not doubt that he and his prayer are, indeed, unworthy before such infinite Majesty; in no wise dare he trust his worthiness, or because of his unworthiness grow faint; but he must heed God's command and cast this up to Him, and hold it before the devil, and say: "Because of my worthiness I do nothing, because of my unworthiness I cease from nothing. I pray and work only because God of His pure mercy has promised to hear and to be gracious to all unworthy men, and not only promised it, but He has also most sternly, on pain of His everlasting displeasure and wrath, commanded us to pray, to trust and to receive. If it has not been too much for that high Majesty so solemnly and highly to obligate His unworthy worms to pray, to trust, and to receive from Him, how shall it be too much for me to take such command upon myself with all joy, however worthy or unworthy I may be?" Thus we must drive out the devil's suggestion with God's command. Thus will he cease, and in no other way whatever.
