The word "lust," constantly used in description of the Satanic system, has a much larger meaning in the Scripture than its present popular use, where it refers only to that which is sensual. In these passages quoted, it refers to the whole Satan-inspired ambition of humanity, and includes their principle of self-help, and their struggle for all that, to them, is highest and best. It is unlawful, in that it disregards the truth of God; and it is related to that which is physical, because it magnifies the finite being and its resources. Two other striking passages concerning the relation of the believer to the world are here given: "Herein is our love made perfect, that we may have boldness in the day of judgment: because as he is, so are we in this world (Satanic system)" (I Jno. 4:17). "As thou hast sent me into the world (Satanic system), even so have I also sent them into the world (Satanic system)" (Jno. 17:18). The last revelation of the believer's position to be mentioned here, is in regard to his service for the world. The unbounded love of God has called him into fellowship with Christ in the great work of this age; and in that connection he is under commission to evangelize, by a process of witnessing, to the uttermost parts of the world. In this undertaking he is promised the immediate presence of Christ, to whom all power, both in heaven and in earth, has been given (Matt. 28:18-20). The language of the inspired Book describes such witnesses as "Ambassadors for Christ": "Now then we are ambassadors for Christ, as though God did beseech you by us: we pray you in Christ's stead, be ye reconciled to God" (II Cor. 5:20). And the ambassador's message is also given in the next verse of the same passage: "For He hath made Him to be sin for us, who knew no sin; that we might be made the righteousness of God in Him" (we who knew no righteousness). Nowhere does the saint need more direct teaching of the Spirit than in regard to the relatioin he sustains to this world. In spite of the similarity of his earth life to that of the world's people, he must reckon himself to be dead in Christ and raised to newness of life. Expecting the world to misunderstand him and even to hate him, he must "wisely walk before them who are without." He is called upon to "use this world but not to abuse it;" and that which is of itself pure and good may become undesirable to him at times, because its use would further the interests of Satan.
