3:13-18 These verses show the difference between men's pretending to be wise, and their being really so. He who thinks well, or he who talks well, is not wise in the sense of the Scripture, if he does not live and act well. True wisdom may be know by the meekness of the spirit and temper. Those who live in malice, envy, and contention, live in confusion; and are liable to be provoked and hurried to any evil work. Such wisdom comes not down from above, but springs up from earthly principles, acts on earthly motives, and is intent on serving earthly purposes. Those who are lifted up with such wisdom, described by the apostle James, is near to the Christian love, described by the apostle Paul; and both are so described that every man may fully prove the reality of his attainments in them. It has no disguise or deceit. It cannot fall in with those managements the world counts wise, which are crafty and guileful; but it is sincere, and open, and steady, and uniform, and consistent with itself. May the purity, peace, gentleness, teachableness, and mercy shown in all our actions, and the fruits of righteousness abounding in our lives, prove that God has bestowed upon us this excellent gift.

As in the case of the earthly wisdom, after the characteristic description came its results; so in this verse, in the case of the heavenly wisdom. There the results were present; here, future.

fruit … sown—Compare Ps 97:11; Isa 61:3, "trees of righteousness." Anticipatory, that is, the seed whose "fruit," namely, "righteousness," shall be ultimately reaped, is now "sown in peace." "Righteousness," now in germ, when fully developed as "fruit" shall be itself the everlasting reward of the righteous. As "sowing in peace" (compare "sown in dishonor," 1Co 15:43) produces the "fruit of righteousness," so conversely "the work" and "effect of righteousness" is "peace."

of them that make peace—"by (implying also that it is for them, and to their good) them that work peace." They, and they alone, are "blessed." "Peacemakers," not merely they who reconcile others, but who work peace. "Cultivate peace" [Estius]. Those truly wise towards God, while peaceable and tolerant towards their neighbors, yet make it their chief concern to sow righteousness, not cloaking men's sins, but reproving them with such peaceable moderation as to be the physicians, rather than the executioners, of sinners [Calvin].
