13 Go to now. He condemns here another kind of presumption, that many, who ought to have depended on God’s providence, confidently settled what they were to do, and arranged their plans for a long time, as though they had many years at their own disposal, while they were not sure, no not even of one moment. Solomon also sharply ridicules this kind of foolish boasting, when he says that
“men settle their ways in their heart, and the Lord in the mean time rules the tongue.” (Proverbs 16:1.)
And it is a very insane thing to undertake to execute what we cannot pronounce with our tongue. James does not reprove the form of speaking, but rather the arrogance of mind, that men should forget their own weakness, and speak thus presumptuously; for even the godly, who think humbly of themselves, and acknowledge that their steps are guided by the will of God, may yet sometimes say, without any qualifying clause, that they will do this or that. It is indeed right and proper, when we promise anything as to future time, to accustom ourselves to such words as these, “If it shall please the Lord,” “If the Lord will permit.” But no scruple ought to be entertained, as though it were a sin to omit them; for we read everywhere in the Scriptures that the holy servants of God spoke unconditionally of future things, when yet they had it as a principle fixed in their minds, that they could do nothing without the permission of God. Then as to the practice of saying, “If the Lord will or permit,” it ought to be carefully attended to by all the godly.
But James roused the stupidity of those who disregarded God’s providence, and claimed for themselves a whole year, though they had not a single moment in their own power; the gain which was afar off they promised to themselves, though they had no possession of that which was before their feet.
