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.
