1:12-18 It is not every man who suffers, that is blessed; but he who with patience and constancy goes through all difficulties in the way of duty. Afflictions cannot make us miserable, if it be not our own fault. The tried Christian shall be a crowned one. The crown of life is promised to all who have the love of God reigning in their hearts. Every soul that truly loves God, shall have its trials in this world fully recompensed in that world above, where love is made perfect. The commands of God, and the dealings of his providence, try men's hearts, and show the dispositions which prevail in them. But nothing sinful in the heart or conduct can be ascribed to God. He is not the author of the dross, though his fiery trial exposes it. Those who lay the blame of sin, either upon their constitution, or upon their condition in the world, or pretend they cannot keep from sinning, wrong God as if he were the author of sin. Afflictions, as sent by God, are designed to draw out our graces, but not our corruptions. The origin of evil and temptation is in our own hearts. Stop the beginnings of sin, or all the evils that follow must be wholly charged upon us. God has no pleasure in the death of men, as he has no hand in their sin; but both sin and misery are owing to themselves. As the sun is the same in nature and influences, though the earth and clouds, often coming between, make it seem to us to vary, so God is unchangeable, and our changes and shadows are not from any changes or alterations in him. What the sun is in nature, God is in grace, providence, and glory; and infinitely more. As every good gift is from God, so particularly our being born again, and all its holy, happy consequences come from him. A true Christian becomes as different a person from what he was before the renewing influences of Divine grace, as if he were formed over again. We should devote all our faculties to God's service, that we may be a kind of first-fruits of his creatures.

17. gift … gift—not the same words in Greek: the first, the act of giving, or the gift in its initiatory stage; the second, the thing given, the boon, when perfected. As the "good gift" stands in contrast to "sin" in its initiatory stage (Jas 1:15), so the "perfect boon" is in contrast to "sin when it is finished," bringing forth death (2Pe 1:3).

from above—(Compare Jas 3:15).

Father of lights—Creator of the lights in heaven (compare Job 38:28 [Alford]; Ge 4:20, 21; Heb 12:9). This accords with the reference to the changes in the light of the heavenly bodies alluded to in the end of the verse. Also, Father of the spiritual lights in the kingdom of grace and glory [Bengel]. These were typified by the supernatural lights on the breastplate of the high priest, the Urim. As "God is light, and in Him is no darkness at all" (1Jo 1:5), He cannot in any way be the Author of sin (Jas 1:13), which is darkness (Joh 3:19).

no variableness … shadow of turning—(Mal 3:6). None of the alternations of light and shadow which the physical "lights" undergo, and which even the spiritual lights are liable to, as compared with God. "Shadow of turning," literally, the dark "shadow-mark" cast from one of the heavenly bodies, arising from its "turning" or revolution, for example, when the moon is eclipsed by the shadow of the earth, and the sun by the body of the moon. Bengel makes a climax, "no variation—not even the shadow of a turning"; the former denoting a change in the understanding; the latter, in the will.
