But if "adulteresses" is taken in the figurative sense, there is still the friendship of the world that is enmity with God. The friendship of the world is preferred to that of God. "World"[87] here is not the earth with all its beauty and charm (God's world made by him; cf. Psalm 19), nor mankind, for whom Christ died (John 3:16), but that world of selfish pleasure and sin out of which Christ called his disciples and which in turn hated them as it hated Christ (John 15:18 ff.). This world will only love as a familiar friend those who cater to its ideals and standards, who condone its slackness of morals and neglect of God.
This cleavage between the wayward, wicked world and the kingdom of God is a fact of the utmost significance (John 17:15 ff.). The Christian has to learn the secret of living in such a worldly atmosphere without being contaminated by it. One does not wish to be considered a religious crank and queer. He desires to have influence with his friends and business acquaintances. But one cannot be a "hail fellow well met" in sin and every form of worldly indulgence and retain his influence for God. The time comes when a choice must be made between friends, for that sort of life in the world becomes incompatible with friendship with God. One must make his choice. "If any man love the world, the love of the Father is not in him" (1 John 2:15). One cannot run with the hare and the hounds. The devil makes no objection to such a double life of hypocrisy, but God does. God is gracious and forgiving to sinners who repent but has no mercy for presumptuous sinners who defy his kindness and keep in touch with the devil and his circles of evil.
The word "enmity" is the term for personal hostility. Preference for sin constitutes a personal offense toward God, who can have no rival, any more than a true wife can suffer a rival in the affections of her husband. "The mind of the flesh is enmity against God" (Rom. 8:7). One must make his choice. "No man can serve two masters: for either he will hate the one, and love the other; or else he will hold to one, and despise the other. Ye cannot serve God and mammon" (Matt. 6:24). Plummer argues clearly that James does not condemn the scientist's love of nature or the sociologist's enthusiasm, which is not always shared in by preachers as much as is desirable.
