I should count the days, not by what I have of new instances of usefulness, but by the times I have been enabled to pray in faith, and to take hold upon God. Prayer should make room for itself; it should interweave itself into all work for Christ. In the incessant occupations, the bustle of even right things, Satan may find his opportunity to hinder prayer. The devil is aware that one hour of close fellowship, of hearty converse with God in prayer, is able to pull down what he hath been contriving and building many a year; Satan, like the lapwing, drew me away from the real object (prayer and fellowship with God) by suggesting every now and then something about some other part of my work…and so the best hours of yesterday were in a great measure lost, so far as ‘prayer and transfiguration’ might have been.
