The case in hand is an illustration of the blessing found in such meek preference for God's pleasure. If it were the will of the Lord that this Continental tour should be undertaken at that time, difficulties need not cast him down; for the _difficulties could not be of God;_ and, if not of God, they should give him no unrest, for, in answer to prayer, they would all be removed. If, on the other hand, this proposed visit to the Continent were _not_ God's plan at all, but only the fruit of self-will; if some secret, selfish, and perhaps subtle motive were controlling, then indeed hindrances might well be interferences of God, designed to stay his steps. In the latter case, Mr. Muller rightly judged that difficulties in the way would naturally vex and annoy him; that he would not like to look at them, and would seek to remove them by his own efforts. Instead of giving him an inward satisfaction as affording God an opportunity to intervene in his behalf, they would arouse impatience and vexation, as preventing self-will from carrying out its own purposes. Such discriminations have only to be stated to any spiritual mind, to have their wisdom at once apparent. Any believing child of God may safely gauge the measure of his surrender to the will of God, in any matter, by the measure of impatience he feels at the obstacles in the way; for in proportion as self-will sways him, whatever seems to oppose or hinder his plans will disturb or annoy; and, instead of quietly leaving all such hindrances and obstacles to the Lord, to deal with them as He pleases, in His own way and time, the wilful disciple will, impatiently and in the energy of the flesh, set himself to remove them by his own scheming and struggling, and he will brook no delay. Whenever Satan acts as a hinderer (1 Thess. ii. 18) the obstacles which he puts in our way need not dismay us; God permits them to delay or deter us for the time, only as a test of our patience and faith, and the satanic hinderer will be met by a divine Helper who will sweep away all his obstacles, as with the breath of His mouth.
