Christ and the world are not in partnership. The apostle says, “Know ye not that the friendship of the world is enmity with God?” ... Conformity to the world will never be the means of converting the world to Christ. Christians must be entirely consecrated to God if the church is to be efficient in its influence for good upon unbelievers.

A Christian, as described by the Scriptures, is a person who is separated from the world in his aims and practices and is united with Christ—a possessor of the peace which Christ alone can bestow, finding that the joy of the Lord is his strength and that his joy is full.

Those who truly love Christ ... watch for every opportunity to employ the means at their command in doing good and in patterning after the works of Christ. They will not yield to temptations to make alliances with the world. They will not unite with secret orders and bind themselves by intimacies with unbelievers.

God has His faithful witnesses who are not attempting to do that which Christ has pronounced impossible—that is, seeking to serve God and Mammon at the same time. They are burning and shining lights amid the moral darkness of the world and amid the gross darkness that covers the people like the pall of death. HP 168
The Scriptures teach men how they should approach their Maker—with humility and awe, through faith in a divine Mediator. Pr 210
"Ye adulterers and adulteresses, know ye not that the friendship of the world is enmity with God? whosoever therefore will be a friend of the world is the enemy of God." James 4:4 (King James Version)
