James i. 12-15
But he must have found special reason for this warning in the peculiar state of these churches; and the explanation is to be sought in that same spirit of externalizing, of which we have already spoken. As this spirit shows itself in the conception of what is good, so does it also in the conception of sin. At no time have there been wanting grounds of excuse for sin; which men have regarded as something cleaving to them from without, and have sought its origin in merely external causes, instead of tracing it to its inward source in the faulty direction of the will. So it would seem that many in these churches excused themselves, on the plea that they were in subjection to a higher power, which hurried them away into sin. The Almighty, whom no one is able to withstand, has plunged them into these temptations. To this James replies: "Let no man say when he is tempted, I am tempted of God;" for as God cannot be tempted by aught that is evil, being elevated above all evil, so neither from him can temptation to sin proceed. The Holy One can tempt none to sin. He then lays open the fountain of temptation in man's own bosom, and describes the process by which the sinful tendency gains ground in progressive steps, till its final development in outward act. The source of temptation, he represents as lying in those desires inherent in every man, by which he is excited and led away; which lie in wait for him, as it were, but which he has power to withstand. They gain strength only because they are not resisted; because he who might subject them to himself, submits himself to them. Thus prevailing, thus ripened into fruit, lust bringeth forth sin; and sin completed in act is followed by death.
We are by no means to infer, as is clear from the connection of thought in this passage, that these desires are not in their own nature sinful; or that the prevailing sinful tendency of the will would not involve death, even if it should find no expression in outward act, as though all turned on the outward act alone. The thought is this: Evil, from the first breaking forth of desire, proceeds on in ascending stages of development, until, -- overpowering all the opposing influences of the higher life, -- it is consummated in act. In this consummation in act is shown an increased strength of sin; and though man was previously able, by overcoming the enticements to sin, to maintain and to reestablish in himself the true life; yet now, through sin which has gained the victory over him, he falls a prey to death. James, therefore, warns them against indulging in such false and delusive ideas, as that God can be the author of evil.
