Still less is there any sin in "the enthusiasm of humanity," in a passionate zeal for the amelioration of the whole human race. A consuming love for one's fellow-men is so far from involving enmity to God that it is impossible to have any genuine love of God without it. "He that loveth not his brother whom he hath seen cannot love God whom he hath not seen" (1 John iv. 20). The love of the world which St. James condemns is a passion which more than anything else renders a love of mankind impossible. Its temper is selfishness, and the principle of its action is the conviction that every human being is actuated by purely selfish motives. It has no belief in motives of which it has no experience either in itself or in those among whom it habitually moves. Next to a cultivation of the love of God, a cultivation of the love of man is the best remedy for the deadly paralysis of the heart which is the inevitable consequence of _choosing_ to be a friend of the world. This choice is a very important element in the matter. It is lost in the Authorized Version, but is rightly restored by the Revisers. "Whosoever, therefore, _would be_ (βουλληθῇ εἶναι) a friend of the world _maketh himself_ (καθίσταται) an enemy of God." It is useless for him to plead that he has no wish to be hostile to God. He has of his own free will adopted a condition of life which of necessity involves hostility to Him. And he has full opportunity of knowing this; for although the world may try to deceive him by confusing the issue, God does not. The world may assure him that there is no need of any choice: he has no need to abandon God; it is quite easy to serve God, and yet remain on excellent terms with the world. But God declares that the choice must be made, and that it is absolute and exclusive. "And now, Israel, what doth the Lord thy God require of thee, but to fear the Lord thy God, to walk in all His ways, and to love Him, and to serve the Lord thy God with _all_ thy heart and with _all_ thy soul, to keep the commandments of the Lord, and His statutes, which I command thee this day for thy good?" (Deut. x. 12, 13; comp. vi. 5 and xxx. 6). The next two verses are a passage of known difficulty, the most difficult in this Epistle, and one of the most difficult in the whole of the New Testament. In the intensity of his detestation of the evil against which he is inveighing, St. James has used condensed expressions which can be understood in a variety of ways, and it is scarcely possible to decide which of the three or four possible meanings is the one intended. But the question has been obscured by the suggestion of explanations which are not tenable. The choice lies between those which are given in the margin of the Revised Version and the one before us in the text; for we may safely discard all those which depend upon the reading "_dwelleth_ in us" (κατῴκησεν), and we must stand by the reading "_made to dwell_ in us" (κατῴκισεν).
