On the previous Lord's day we considered the first great enemy of our soul, Satan. To-day we come to the second, the world, reserving the third, the flesh, God willing, for next Sunday. To deal practically and directly with the matter, let us ask the questions: _I. What is worldliness, and how can I tell whether I am worldly or not?_ _II. How can I overcome my worldliness?_ And may God's wisdom and blessing attend our meditation! If we read our Bible carefully, my beloved, we shall be impressed, overwhelmed by the number of Scripture passages which refer to God's people and their relation to this world. These passages are found in the Old Testament and in the New, and they are plain-spoken, their own interpretation. In the Old Testament they are such as these: "Deliver my soul from men of the world, who have their portion in this life." "And ye shall be holy unto me, for I, the Lord, am holy, and have severed you from other people, that ye should be mine." In the New Testament we find the passages still more explicit and manifold. To begin with, there is nothing that Jesus teaches with greater frequency or with greater positiveness than this fact, that we are to be unworldly in our Christian life. "Ye are not of the world," He declares, "for I have chosen you out of the world." "Ye cannot serve God and mammon." "What shall it profit a man if he should gain the whole world and lose his own soul?" And as the Master, so His apostles. "Be not conformed," exhorts Paul, "to this world." "Be not unequally yoked together with unbelievers." "Come out from among them, and be ye separate." James writes: "The friendship of the world is enmity with God. Whosoever will be a friend of the world is the enemy of God." "True religion before God is to keep oneself unspotted from the world." And to finish our quotations with the words of St. John: "Love not the world, neither the things that are in the world. If any one love the world, the love of the Father is not in him." There is nothing uncertain about these statements. Their teaching is clear. They declare that there is a broad and ineffaceable line of demarcation between the people of God and the world. They are so far apart that no man can belong to both at the same time. To try to do so produces an absurd piety and a sham, is as foolish as trying to mix light and darkness, oil and water. They refuse to mix. It means either--or, one or the other. Either Christianity will have the sway, and it will conquer and eradicate the world, or the world will have the sway, and it will efface Christianity. The world proposes a compromise, it is true, but the compromise always means death; that is why it proposes it. How imperative, then, that we should analyze what worldliness is and plant an interrogation in our heart: Am I worldly?
