We must realize that this world is not God's world! The systems that operate our cultures are not His. The world's systems generate and sustain our government, politics, entertainment, fashion, religion, business ethics, medicine, health care, culinary tastes, social programs, institutions, education, science, technology, economics, and use of power. These systems have formed much of humanity's belief systems and attitudes, which, in turn, have shaped human conduct. Yet this world and its systems are so appealing! God in His wisdom advises us not to waste our love on them because they have no future. In fact, this world is so corrupt that the whole thing will be destroyed and replaced when God invokes the restitution of all things. The basic reason all must be destroyed is because at its very foundation stands a destroying and antagonistic spirit, satan the devil, the ruler of this world. Satan is a destroyer, and his way is at best a deadly mixture of good and evil. So strong is God's warning about the world that He urges us to come out from among them and be separate, not to touch what is unclean, promising that He will receive us and be a Father to us, and we shall be His sons and daughters. Not one part of this system will be carried over into the world to come, for the whole thing is unclean, something that contaminates and defiles, rendering unholy those who are touched by it. The world is most dangerous to Christians when it seems friendly and tolerant, even producing apparently good things, but God declares it still unclean, a poisonous brew of good and evil. In these matters, it is God's judgment that counts.

The concept of the world, as represented by the Greek word cosmos in the New Testament, carries profound spiritual, moral, and ethical implications for the church and its relationship with God. Cosmos is a term the apostles adapted from Greek, transforming its original meaning of order and beauty into a representation of something often evil and opposed to God. In its various applications, cosmos can denote the universe, the earth, its inhabitants, or a specific culture, but its most significant usage pertains to the present order of things, the systems and cultures developed since Adam and Eve. When used in this sense, it consistently bears a negative connotation, portraying the world as transient, worthless, and evil, often seen as the seat of cares, temptations, and irregular desires. Scriptures such as Ephesians 2:1-2 highlight this negativity by linking the course of this world with the prince of the power of the air, depicting a system of disobedience and rebellion against God. Similarly, I John 5:19 states that the whole world lies under the control of the evil one, emphasizing the pervasive influence of satan over worldly systems. Luke 4:5-6 further illustrates this control, where the devil claims authority over all the kingdoms of the world, subject only to the ultimate restraint of God. This reveals the sobering reality of satan's power within the limits permitted by God, underscoring why the apostles frequently describe the world as evil and in opposition to Him. The world's systems, driven by a spirit that is deceitful and incurably sick as described in Jeremiah 17:9, stand in deadly antagonism to God's way. Romans 8:5-8 clarifies that this carnal spirit is enmity against God, incapable of being subject to His law, and thus cannot please Him. This spirit, originating from satan, motivates the unconverted and has shaped the world for six thousand years in a manner that is wholly evil, contrasting sharply with the Spirit of God. Consequently, believers are urged to choose between these two opposing forces, as neither can coexist within the same individual. John 15:18-19 warns that the world hates those chosen out of it by Christ, creating a deep and perpetual antagonism between the church and worldly systems. This hatred stems from the fundamental opposition in principles and the shared contention for possession of the earth. The world's allure, as seen in the example of Demas in II Timothy 4:9-11, poses a constant danger, drawing even the converted away from their faith through its attractions and seductions. Thus, believers must remain vigilant, recognizing that the world's systems, influenced by the unseen prince of this world, are in deadly opposition to God and His people, necessitating a steadfast guard against its deceptive appeal.
