The “immediate” person thinks and imagines that when he prays, the important thing, the thing he must concentrate upon, is that God should hear what he is praying for. Yet in the true, eternal sense it is just the reverse: the true relation in prayer is not when God hears what is prayed for, but when the person praying continues to pray until he is the one who hears, who hears what God wills. The “immediate” person, therefore,… makes demands in his prayers; the true man of prayer only attends.
