Separation is scriptural under a variety of different scenarios. Most commonly, believers understand that they are to separate from unbelievers (2 Corinthians 6:14). This does not imply that believers should not witness to the lost but that there should be no “fellowship” between the two. The Bible also indicates that there are times in which one believer should separate from another believer. Most often, this happens because of the propagation of false doctrine (Romans 16:17-18; 2 Thessalonians 3:6) or immoral practices (1 Corinthians 5:11). However, there may also be instances when believers separate for the purpose of furthering the work of God (Galatians 2:6-9).
Man-made religions have always unwisely taught followers to establish their own righteousness. In the garden in Eden, Adam and Eve clothed themselves with fig leaves in an attempt to cover their nakedness caused by sin. Men built the tower of Babel hoping that this device could help them reach into heaven. The Bible describes man’s righteousness as “filthy rags” (Isaiah 64:6). Today's passage tells of a people who went about to establish their own righteousness by refusing to submit to God’s righteousness. Man-made religions all err in the same way. They think that some work or act of obedience can somehow establish a level of righteousness that will ultimately and eventually satisfy God. Yet, the Bible points out the repeated futility of failing to submit to the righteousness of God.
