Such as Paul hints at in 1 Corinthians 14:26-33, where many voices of would-be teachers contended for a hearing. James would check that unwholesome eagerness by the thought that teachers who do not practice what they preach will receive a heavier judgment than those who did not set up to be instructors. He humbly classes himself with the teachers. The for' of James 3:2 introduces a reason for the advice in James 3:1--since it is hard to avoid falls, and harder in respect to speech than action, it is a dangerous ambition to be a teacher.
That thought leads on to the series of considerations as to the government of the tongue. He who can completely keep it under command is a perfect' man, because the difficulty of doing so is so great that the attainment of it is a test of perfection. James is like the Hebrew prophets, in that he does not so much argue as illustrate. His natural speech is imagery, and here he pours out a stream of it. The horse's bridle and the ship's rudder may be taken together as both illustrating the two points that the tongue guides the body, and that it is intended that the man should guide the tongue. These two ideas are fused together here. The bridle is put into the mouth, and what acts on the mouth influences the direction of the horse's course. The rudder is but a little bit of wood, but its motion turns the great ship, even when driven by wild winds. So the tongue is a little member, and boasteth great things,' which boasting is not false, for the whole point of the passage is that that little member has large power.
Is it true, as James says, that it governs our actions as the bridle does the horse, or the rudder the ship? No doubt, many sins go straight from the inner chambers of the heart's desires out into the world of action without going round by the way of speech; but still, if we think of the immense power of our own words and of others in setting our activities in motion, of the dreadful harvest of sin which has often sprung from one tempting word, of the ineffaceable traces of pollution which some vile book leaves in memory and heart, of the good and evil which have been wrought by spoken or printed words, and that never more truly than to-day, when a flood of talk all but drowns the world, we shall not think James exaggerating in the awful weight he gives to speech as the mother of action.
His other point is that this guiding power needs guidance. A firm yet gentle hand touches the rein, and the sensitive mouth yields to the light pressure. The steerman's hand pushes or draws the tiller an inch from or towards him, and the huge vessel yaws accordingly. Speech is often loose. Most men set less careful watch on the door of their lips than of their actions; but it would be wiser to watch the inner gate, which leads from thought to speech, than the outer one, which leads from speech to act. Idle words, rash words, unconsidered words, free-flowing words, make up much of our conversation. His tongue ran away with him' is too often true. It is hard but possible, and it is needful, to guide the helm, to keep a tight hand on the reins.
