Hudson Taylor's Quiet Time
It was not easy for Mr. Taylor, in his changeful life, to make time for prayer and Bible study, but he knew that it was vital. Well do the writers remember traveling with him month after month in northern China, by cart and wheelbarrow with the poorest of inns at night. Often with only one large room for coolies and travelers alike, they would screen off a corner for their father and another for themselves, with curtains of some sort; and then, after sleep at last had brought a measure of quiet, they would hear a match struck and see the flicker of candlelight which told that Mr. Taylor, however weary, was pouring over the little Bible in two volumes always at hand. From two to four A.M. was the time he usually gave to prayer; the time he could be most sure of being undisturbed to wait upon God
