8. Now, in order to understand the nature of the spiritual victory and how it is effected, we must know just what John means by the term "world." The reference is not to dominion over territory, to property or money. He implies the existence of two kingdoms. In one, the kingdom of God, the heavenly kingdom of Christ, is included, first, the angels in heaven, who are the chief lords, the inner circle of counselors; second, the entire Christian Church on earth, under one head, Christ the Lord and King. In the other kingdom, the hellish kingdom, the devil is prince, and his mighty counselors and servants are the angels who with him fell from heaven; it also includes the world, those on earth who teach, believe and live contrary to Christ, who represent the heathen, the Jews, the Turks and false Christians.
By the heavenly kingdom of God we must understand, not only spiritual life and godly people, but the lord and regent of that kingdom—Christ with his angels, and his saints both living and dead. Thus, too, the kingdom of the world represents not only the earthly life with its worldly interests, but particularly its lord and regent—the devil and his angels, and all unchristian, godless, wicked people on earth. So, when John says, "Whatsoever is begotten of God overcometh the world," he means by "world" the devil and his whole earthly dominion.
9. Now, the workings of these two kingdoms are plainly evident, though the leaders—Christ the Lord, and the devil—are not visible to mortal eyes. Christ rules direct and effectually, in his own power, through the Word and through the Holy Spirit in the hearts of believers, maintaining them in the faith and in the knowledge of his Word, and protecting from the devil's wrath and subtlety; further, he rules through his angels, who guard his followers; again, he rules through his people themselves, who exercise authority one over another in loving service, each teaching, instructing, comforting and admonishing a noble little band of godly, obedient, patient, chaste, kind, tractable, benevolent souls.
The nature of the devil's kingdom, the manner of life the world leads, is easily apparent. This kingdom is simply a huge booth filled with faithless, shameless, wicked individuals, impelled by their god to every sort of disobedience, ingratitude and contempt of God and his Word; to idolatry, false doctrine, persecution of Christians and the practice of all wantonness, mischief, wickedness and vice.
10. These two kingdoms are opposed. They continually contend for the crown; they war with each other for supremacy. Christians are brought into the conflict to hold the field against God's enemy, whose rule of the world is one of falsehood and murder; they must contend with the enemy's servants, his horde of factious spirits and basely wicked individuals, in an effort to restrain evil and promote good. Christians must be equipped for the fray; they must know how to meet and successfully resist the enemy, how to carry the field unto victory, and hold it.
