In reality they are not simple. To have the right thing to say is a great commandment, and to know the right way to say it is, though second to it, hardly inferior. But the problem of the ministry is to have both in perfect equipoise--to utter a word which is at the same time both a message from God and a message to men. It would be possible to be so taken possession of by the message from God as to lose self-control and even reason itself. In Scripture we meet with manifestations of prophecy which are akin to madness. Just as the wind, catching the sail, would, if the ropes were not adjusted to relieve the strain, overturn the boat, so the Wind of God might sweep the mind off its balance, the human personality being overborne by the inrushing inspiration. Thus religion may make a man a fanatic, who has no control over his own spirit, and no wisdom to choose the times at which to speak or the terms in which to address his fellow-men. On the other hand, the opposite excess is still more easy. So much stress may be laid on the form of words, and so much mastery obtained of the art of winning attention, that the necessity of having a Divine message to deliver or of depending on the power of the Spirit of God is forgotten. The windy master of words, whose own spirit is not subdued either by the impression of great thoughts or the sense of a great responsibility, but who can draw the eyes of men on his own performances and earn the incense of applause, has always been too familiar a figure in religion. It is to a man like Isaiah we must look for the absolute balance of both sides. There you have the blowing in all its degrees of the Wind of God, from the gentlest whisper to the force of the tempest, but, at the same time, the most perfect self-control and the adaptation of the word to the tastes and necessities of those to whom it was delivered.
