The church must stand apart from the world, resisting its spiritual contamination as urged by the apostles. In obedience to I John 2:15-17, believers are called to avoid the world's allure, a principle echoed by James in his exhortation to remain unspotted from the world (James 1:27), and by Paul in Romans 12:2, where he implores us not to conform to this world but to be transformed by the renewing of our minds to prove the good, acceptable, and perfect will of God. This world is not God's world; its systems, which shape government, entertainment, fashion, religion, business, and more, are apart from Him, driven by false values and sustained by the antagonistic spirit of Satan, the ruler of this world. God's wisdom advises against wasting love on these systems, for they have no future and will be destroyed and replaced in the restitution of all things. So strong is God's warning that through Paul in II Corinthians 6:14-18, He commands believers not to be unequally yoked with unbelievers, highlighting the incompatibility of righteousness with lawlessness, light with darkness, and Christ with Belial. He calls His people to come out from among them, to be separate, and to avoid touching what is unclean, promising to receive them as His sons and daughters. This system, deemed unclean and defiling, will not be carried into the world to come. Even when the world appears friendly and tolerant, producing seemingly good things, it remains dangerous to Christians, for its mixture of good and evil still yields a poisonous brew. In these matters, it is God's judgment that must guide us, prompting a reevaluation of any worldly habits or practices that may have crept into our relationship with Him.

The church stands alone as a unique institution formed by God, not of men in any way, shape, or form. It consists only of those whom He personally calls, and the honor of this calling is almost beyond significant, stunning in its possibilities. We must treasure this opportunity and not waste it, for we have been given a spiritual gift of immense value. The church is a separate group within God's purpose, absolutely forbidden to be involved in the world for spiritual reasons. Unlike the churches of this world, which are often filled with fine, moral, and sincere people but are deeply involved in politics, wars, fundraising for worldly charities, and operating hospitals, the church's purpose is distinct. These activities, while not evil in themselves, are not what the Bible shows as our responsibility in behalf of God's purpose. The churches of the world see themselves as part of this world's system, not sanctified from it, failing to take seriously their identity as citizens of Heaven. They do not act on the citizenship responsibilities that God requires of those who are part of His Kingdom. As citizens of Heaven, we have separated ourselves from the world and all its systems. Our primary responsibility is to God, and only secondarily to anything in this world. We do not enter their wars or political systems, even though we are good citizens in other respects. Legally, as citizens of Heaven, we are not given permission by God to participate in this world's systems, which can cause persecution, but this separation is our responsibility. Following Christ is how each Christian should live individually. He was not part of this world, nor was He accepted by it. If we follow Him step-for-step as commanded, we imitate Him in all things. He did not participate in elections or wars; He served the world by dying for those who follow Him. As members of His body, we go where He went and do what He did, keeping the Sabbath, the holy days, and adhering to His example of baptism by immersion. The separation of the church from the world is evident when we observe that the world does not follow the commandments of God, which is what distinctly sets us apart. The church's primary purpose as the body of Jesus Christ is as a teaching institution. It fulfills this responsibility by making known to the world at large the overall purpose God is working out and by further educating those invited to participate more directly in God's way of life. The church preaches the gospel to the world as a generality, while to its members, it provides a magnified, detailed education, preparing them for the Kingdom of God through teaching, learning, and actual practice. This dual work of preaching to the world and feeding the flock separates the church, as it alone is qualified to preach the true gospel, being part of the body of Christ with a direct connection to Him.

The church, as seen in the New Testament, is distinctly separated from the world, reflecting a pattern established by God from the beginning. Unlike Israel, which was called to drive out or destroy the inhabitants of the land God gave them, the church is not established on any specific earthly territory and holds no civil or military power. According to Philippians 3, the citizenship of the church is in heaven, not on earth. The world, under the sway of Satan as described in I John 5, is at war with God, and the Christian is viewed as an alien and a pilgrim within it. God commands His people to come out from among the world and be separate, as stated in II Corinthians 6:17. This separation is not merely physical but involves ceasing to think, act, or hold the same attitudes as the world. God, like a concerned parent, desires His children to have as little contact with the world's influences as possible, fearing that the world will pull them down due to their lack of spiritual strength to resist. Instead, Christians are instructed to seek God, making Him the focus of their lives and seeking the place where He has placed His name. In the New Testament, the concern is not with physical idols or buildings but with attitudes, beliefs, and practices spread among the people of the world by spiritual entities, referred to as gods many and lords many. These influences manifest in the world's institutions, government, education, religion, business practices, social programs, entertainment, and more, all of which are rarely in harmony with God's laws. The Christian's worldview must stem from a fear of God, as exemplified by Nehemiah, rather than from the world's perspective. James 4 warns Christians against becoming friends with the world, as this makes them enemies of God and leads to spiritual adultery by adopting worldly attitudes. The world remains God's enemy, unchanged in its opposition from the Old Testament to the New, though the focus under the New Covenant is on the root spiritual causes of the problem. God prioritizes the church over the world, setting clear responsibilities: first to Him, then to family, then to the church, and finally to everything else. Efforts to change the world are seen as vain and futile since it is destined for destruction, and true change can only occur through God's Spirit, which He selectively grants. The Bible differentiates levels of conduct between God's people and the world. While Christians are to love their enemies, as instructed in Matthew 5, this love is not to the same degree as loving a brother in Christ as oneself. The command to love one's neighbor as oneself applies specifically to brethren within the church, those who have made the covenant with God, as seen in both Old and New Testament contexts. Opportunities to do good in the world are to be taken as they arise, but they are not to detract from the primary focus on seeking first the Kingdom of God. God sees two distinct classes on earth: His people, who submit to Him and strive to conform to His government, and the world, under the sway of the wicked one and full of dangerous temptations to His plans. He commands His people not to love the world or befriend it, lest they become His enemies. The Bible's testimony is that the world killed Christ and hates the church, posing a constant threat to spiritual growth. If even necessary contact with the world turns believers aside, it can severely affect their growth and possibly cost them their salvation. God's program, designed to create His people in His image, demands their full attention and adherence to the priorities set in His Word.
