19 Let every man. Were this a general sentence, the inference would be farfetched; but as he immediately adds a sentence respecting the word of truth suitable to the last verse, I doubt not but that he accommodates this exhortation peculiarly to the subject in hand. Having then set before us the goodness of God, he shews how it becomes us to be prepared to receive the blessing which he exhibits towards us. And this doctrine is very useful, for spiritual generation is not a work of one moment. Since some remnants of the old man ever abide in us, we must necessarily be through life renewed, until the flesh be abolished; for either our perverseness, or arrogance, or sloth, is a great impediment to God in perfecting in us his work. Hence, when James would have us to be swift to hear, he commends promptitude, as though he had said, “When God so freely and kindly presents himself to you, you also ought to render yourselves teachable, lest your slowness should cause him to desist from speaking.”
But inasmuch as we do not calmly hear God speaking to us, when we seem to ourselves to be very wise, but by our haste interrupt him when addressing us, the Apostle requires us to be silent, to be slow to speak. And, doubtless, no one can be a true disciple of God, except he hears him in silence. He does not, however, require the silence of the Pythagorean school, so that it should not be right to inquire whenever we desire to learn what is necessary to be known; but he would only have us to correct and restrain our forwardness, that we may not, as it commonly happens, unseasonably interrupt God, and that as long as he opens his sacred mouth, we may open to him our hearts and our ears, and not prevent him to speak.
Slow to wrath. Wrath also, I think, is condemned with regard to the hearing which God demands to be given to him, as though making a tumult it disturbed and impeded him, for God cannot be heard except when the mind is calm and sedate. Hence, he adds, that as long as wrath bears rule there is no place for the righteousness of God. In short, except the heat of contention be banished, we shall never observe towards God that calm silence of which he has just spoken.
