"My many words on the subject can be summed up by a few: Be simply and wholly bereft of ‘self.’
Now some say, “I am not prepared for this work, and therefore it cannot be produced in me.”
Thus, they find an excuse, so they are neither prepared nor in the way to be prepared….
But if you were looking and striving after nothing but to find a preparation in all things and diligently gave your whole mind
to see how you might become prepared, then truly God would well prepare you. For God gives as much care and love
and earnest resolve to preparing you as to the pouring in of the Spirit once you are prepared."
-Theologia Germanica, 14 th century
