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).
We should not assume that our contentions for the truth will always be directed toward those who know not the Lord. Unfortunately, our stand for truth will often be opposed by the very ones who claim to know the Lord as Saviour. Nehemiah serves as a great example of someone who stood for the Lord against severe opposition from his brethren. In the thirteenth chapter of the book that bears his name, the Bible records his stand against those who were set apart by the Lord. He contended with them for the house of the Lord (Nehemiah 13:11), the law of the Lord (Nehemiah 13:15-22), and the purity of their homes (Nehemiah 13:23-26). Just as Nehemiah contended with those who knew the Lord, God may call upon us to do the very same thing.
