James 1:15

The guilty union is committed by the will embracing the temptress. "Lust," the harlot, then, "brings forth sin," namely, of that kind to which the temptation inclines. Then the particular sin (so the Greek implies), "when it is completed, brings forth death," with which it was all along pregnant [ALFORD]. This "death" stands in striking contrast to the "crown of life" (Jam 1:12) which "patience" or endurance ends in, when it has its "perfect work" (Jam 1:4). He who will fight Satan with Satan's own weapons, must not wonder if he finds himself overmatched. Nip sin in the bud of lust.

After the inscription and salutation (Jam 1:1) Christians are taught how to conduct themselves when under the cross. Several graces and duties are recommended; and those who endure their trials and afflictions as the apostle here directs are pronounced blessed and are assured of a glorious reward (Jam 1:2-12). But those sins which bring sufferings, or the weakness and faults men are chargeable with under them, are by no means to be imputed to God, who cannot be the author of sin, but is the author of all good (Jam 1:13-18). All passion, and rash anger, and vile affections, ought to be suppressed. The word of God should be made our chief study: and what we hear and know of it we must take care to practise, otherwise our religion will prove but a vain thing. To this is added an account wherein pure religion consists (Jam 1:19-27).

1:15 When evil desires conceive, they give birth to sinful actions (literally sin, personified as an infant). When the infant sin is allowed to grow to full maturity, it gives birth to death, in opposition to “the crown of [eternal] life” (1:12).
