10. Under the phrase "things that are upon the earth"--worldly things--Paul includes not only gross, outward vices, sins censurable in the eyes of the world, but also greater immoralities; everything, in fact, not in accordance with the pure Word of God, faith and true Christian character. SPIRITUAL AND CARNAL WORLDLINESS. 11. In order to a better understanding of the text, we shall adopt Paul's customary classification of life as spiritual and carnal. Life on earth is characterized as of the spirit, or spiritual; and of the flesh, or carnal. But the spiritual life may be worldly. The worldly spiritual life is represented by the vices of false and self-devised doctrine wherein the soul lives without the Word of God, in unbelief and in contempt of God; or, still worse, abuses the Word of God and the name of Christ in false doctrine, making them a cover and ornament for wicked fraud, using them falsely under a show of truth, under pretense of Christian love. This is worldly conduct of the spiritual kind. It is always the worst, ever the most injurious, since it is not only personal sin, but deceives others into like transgression. Paul refers, in the epistle lesson for Easter, to this evil as the "old leaven" and the "leaven of wickedness." And in Second Corinthians 7, 1, he makes the same classification of spiritual and carnal sin, saying, "Let us cleanse ourselves from all defilement of flesh and spirit." By defilement of the spirit he means those secret, subtle vices wherewith man pollutes and corrupts his inner life in the sight of God; his sins not being manifest to the world, but deceiving human reason and wisdom. 12. If we would be Christians we must, first of all, be dead to conduct of this sort. We must not receive nor tolerate the worldly doctrine and corrupt inventions originating with ourselves, whether in the nature of reason, philosophy or law, theories ignoring the Word of God or else falsely passing under its name. For such are wholly of the world; under their influence man has no regard to God's will and seeks not his kingdom and eternal life. They are meant merely to further the individual's own honor, pride, renown, wisdom, holiness or something else. Though boast is made of the Gospel and of faith in Christ, yet it is not serious, and the individual continues without power and without fruit. 13. If we are risen with Christ through faith, we must set our affections upon things not earthly, corruptible, perishable, but upon things above--the heavenly, divine, eternal; in other words, upon doctrine right, pure and true, and whatever is pleasing to God, that his honor and Christ's kingdom may be preserved. Thus shall we guard ourselves against abuse of God's name, against false worship and false trust and that presumption of self-holiness which pollutes and defrauds the spirit.
