19. He will not strive The general meaning is, that the coming of Christ will not be attended by noise, will have nothing of royal splendor and magnificence. He presently adds, that this will turn to the advantage of men, by inducing them to love that mildness which the world everywhere despises. And certainly it is an astonishing display of the folly of men, that their sentiments with regard to Christ are less respectful, because he mildly and voluntarily accommodates himself to their capacity. Were Christ to appear in his glory, what else could be expected, but that it would altogether swallow us up? What wickedness then is it to be less willing to receive him, when on our account he descends from his elevation?
That the gentleness of Christ may awaken reverence in believers, Isaiah reminds them how advantageous, and even how necessary that gentleness must be. Each of us is conscious of his own weakness; and therefore we ought to consider of what importance it is that Christ should treat us with kindness. I speak not of unbelievers, who are entirely destitute of all the graces of the Spirit; but with respect to those whom God has already called, are they not like a half-broken reed and a smoking lamp, till God kindle them to full brightness, and supply them with perfect strength? When Christ is thus pleased to condescend to our weakness, let his unspeakable goodness be embraced by us with joy. Meanwhile, let none flatter himself in his vices, but let each of us labor to make greater proficiency, that we may not be tossed about (Ephesians 4:14) through our whole life, or bend, like reeds, to the slightest gale. Let us grow to the stature of perfect men, that we may remain firm against the diversified attacks of Satan, that our faith may not only emit slight sparks encompassed by thick smoke, but may send out bright rays.
The example of Christ instructs all his ministers in what manner they ought to conduct themselves. But as there are some who falsely and absurdly maintain that mildness ought to be exercised indiscriminately towards all, we must attend to the distinction which the prophet expressly makes between weak and wicked persons. Those who are too stubborn need to have their hardness beaten violently with a hammer; and those who endeavor to spread darkness in every direction, or who act as torches to kindle conflagrations, must have their smoke dispelled and their flame extinguished. While the faithful ministers of the Word ought to endeavor to spare the weak, and thus to cherish and increase that portion of the grace of God, however small, which they possess, they must also exercise prudent caution, lest they encourage the obstinate malice of those who have no resemblance to the smoking lamp or bruised reed.
