ordinances of religion to every age. As the nation both externally and internally altered, new teaching had to come to it at the hands of the prophets. Were the priests the channel by which God could do it? Their duty was fixed, and in the law, as well as in the form of government, men could not err; they could follow the Divine precepts exactly in administering them. But when an addition has to be made, and a remoulding to take place, it wants a man capable of entering with strange, grand insight into God's purposes, a man with eyes, with soul; it needs a man lifted up. And so the prophets' office was never hereditary; they were always selected; God chose them; why? Why did God choose one man, and not another? I think that He chose a man, first of all, who had a natural adaptation, who had rare powers of mind, who had rare genius and sympathetic feeling, and not a mere presentiment of the movements of the world and its destiny as it went on round about him. I think that, as a rule, God selected a man with a natural adaptation, and prepared him for all that he had to do and tell. It transformed a man's life; it took him clean out of the common world in which men lived. We presume that it was so from what is recorded, and from the facts which we know concerning the prophets' characters and lives. God caused something to happen to a man that made God appear to him what He was not to common men. An awful vision was presented to Isaiah of the great, grand God, and thenceforth all earthly considerations were nothing to Isaiah. He had seen _God_, and the future was God's making. In the face of empires, however mighty in name and in armies, it is the will of God that settles the future, and such a man disregards all earthly advantages; he knows that God means to do His deed; he says, "It shall be done; and if you set yourselves against it there is no other end than destruction, which is sure to fall upon you, for God will do the deed which He means to do." It was a revelation of _God_ which made the man a prophet; it made him a man who felt God to be supreme; it made him to be certain of God's sovereignty, and absoluteness, and the goodness of God's authority; so that nothing could induce him to swerve from the path that God appointed for him. He was a man who stood like a rock amidst the earthly, selfish, planning, scheming men of his time, and declared the future truly, because he had seen God's meaning, and held men to it; and when they would not be so held he was content to die, declaring the truth of his message, and looking forward to the time when the future would manifest its truth. He was a fit prophet, a living teacher, who spoke of the future—a grand man, with a grand office and a grand destiny to play in the world.
