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).
Though peace may seem illusive, God instructs all believers to pursue after it. True inner peace is not something that one can afford to live without. The Bible says, “seek peace, and pursue it.” Peter reiterates this truth by saying, “seek peace, and ensue it” (1 Peter 3:11). Men should seek after peace; and when found, they should allow nothing to prevent them from fully seizing upon it. The Lord said, “therefore love the truth and peace” (Zechariah 8:19). Several New Testament verses repeat the importance of peace by admonishing the believer to follow after it (Romans 14:19; 2 Timothy 2:22; Hebrews 12:14). God certainly wants us to seek peace (1 Corinthians 7:15) and makes peace attainable. Yet, He demands that we pursue after His peace His way because any other peace is really no peace at all.
