This is most simple and deeply practical. We can have no difficulty in seeing its force and application in the case of the congregation in the wilderness. But let us remember that all this was a type; and further, that it is written for our learning. We are solemnly bound, therefore, to look into it; we are imperatively called upon to seek to gather up and treasure up the great practical instruction contained in the singularly beautiful ordinance of the silver trumpet. Nothing could be more seasonable for the present moment. It teaches a lesson to which the Christian reader should give his most profound attention. It sets forth, in the most distinct manner possible, that God’s people are to be absolutely dependent upon and wholly subject to divine testimony in all their movements. A child may read this in the type before us. The congregation in the wilderness dared not assemble for any festive or religious object until they heard the sound of the trumpet; nor could the men of war buckle on their armor till summoned forth by the signal of alarm to meet the uncircumcised foe. They worshiped and they fought, they journeyed and they halted, in simple obedience to the trumpet-call. It was not, by any means, a question of their likings or dislikings, their thoughts, their opinions, or their judgment. It was simply and entirely a question of implicit obedience. Their every movement was dependent upon the testimony of God, as given by the priests from the sanctuary. The song of the worshiper and the shout of the warrior were each the simple fruit of the testimony of God. How beautiful! how striking! how instructive! and, let us add, how deeply practical! Why do we dwell upon it? Because we firmly believe it contains a needed lesson for the day in which our lot is cast. If there is one feature more characteristic than another of the present hour, it is insubjection to divine authority—positive resistance of the truth when it demands unqualified obedience and self-surrender. It is all well enough so long as it is truth setting forth, with divine fullness and clearness, _our_ pardon, _our_ acceptance, _our_ life, _our_ righteousness, _our_ eternal security in Christ. This will be listened to and delighted in; but the very moment it becomes a question of the claims and authority of that blessed One who gave His life to save us from the flames of hell and introduce us to the everlasting joys of heaven, all manner of difficulties are started; all sorts of reasonings and questions are raised; clouds of prejudice gather around the soul, and darken the understanding. The sharp edge of truth is blunted or turned aside, in a thousand ways. There is no _waiting_ for the sound of the trumpet; and when it sounds, with a blast as clear as God Himself can give, there is no response to the summons. We move when we ought to be still, and we halt when we ought to be moving.
