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).
The Lord healed many people during His earthly ministry. Today's passage speaks of a particular man who had been delivered from devil possession. What a relief he must have experienced! However, the people in his community did not rejoice that the Lord had performed such a wonderful miracle. In fact, they turned against the Saviour and wanted Him to depart from their coasts. The Lord complied with their demands; however, the man delivered of the devils wanted to travel with the Lord. He loved the Lord so much that he wanted to stay close to Him. However, as the healed man sought to enter the ship, Christ told him to return to his home and tell his friends what had happened to him. The Lord knew that this man was in the best position to reach out to his friends with the truth. He knew this man's testimony concerning the truth was what they needed to hear and believe. Christians should always be prepared and ready for times when opportunities arise to tell their friends about the truth. Acts chapter 10 records another example when Cornelius called his friends together expecting to hear Simon Peter preach the truth of the gospel. Real friends insure that their friends are put into a position to hear the truth and never squander spiritual opportunities.
