Only twice after this did George Muller ever resort to the lot: once at a literal parting of the ways when he was led by it to take the wrong fork of the road, and afterward in a far more important matter, but with a like result: in both cases he found he had been misled, and henceforth abandoned all such chance methods of determining the mind of God. He learned two lessons, which new dealings of God more and more deeply impressed: First, that the safe guide in every crisis is believing prayer in connection with the word of God. Secondly, that continued uncertainty as to one's course is a reason for continued waiting. These lessons should not be lightly passed over, for they are too valuable. The flesh is impatient of all delay, both in decision and action; hence all carnal choices are immature and premature, and all carnal courses are mistaken and unspiritual. God is often moved to delay that we may be led to pray, and even the answers to prayer are deferred that the natural and carnal spirit may be kept in check and self-will may bow before the will of God. In a calm review of his course many years later George Muller saw that he "ran hastily to the lot" as a shorter way of settling a doubtful matter, and that, especially in the question of God's call to the mission field, this was shockingly improper. He saw also how unfit he had been at that time for the work he sought: he should rather have asked himself how one so ignorant and so needing to be taught could think of teaching others! Though a child of God, he could not as yet have given a clear statement or explanation of the most elementary gospel truths. The one thing needful was therefore to have sought through much prayer and Bible study to get first of all a deeper knowledge and a deeper experience of divine things. Impatience to settle a matter so important was itself seen to be a positive disqualification for true service, revealing unfitness to endure hardship as a good soldier of Jesus Christ. There is a constant strain and drain on patient waiting which is a necessary feature of missionary trial and particularly the trial of deferred harvests. One who, at the outset, could not brook delay in making his first decision, and wait for God to make known His will in His own way and time, would not on the field have had long patience as a husbandman, waiting for the precious fruit of his toil, or have met with quietness of spirit the thousand perplexing problems of work among the heathen!
