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).
Throughout the years, faithful saints have been willing to lay down their lives for the truth. In Acts chapter 7, we read the account of Stephen’s final message to the nation of Israel. His message infuriated the people so much that they ran upon him and threw stones at him until they crushed the life out of his body. Stephen was martyred because he cared more for the truth's propagation than even his own life and welfare. Though most Christians are not living amongst such severe persecution, our willingness to contend should remain just as fervent. We should pray that God would give us some modern believers who, like Paul, would say, “that in nothing I shall be ashamed, but that with all boldness, as always, so now also Christ shall be magnified in my body, whether it be by life, or by death” (Philippians 1:20)!
There are very few matters in this life for which we ought to earnestly contend. Yet “the faith which was once delivered unto the saints” stands as one of those things. “The faith” in this context refers specifically to the body of doctrine delivered to us. As believers, we should always be ready and willing to take a stand for the truths of God’s holy word. This contending does not suggest becoming violent toward those who oppose truth. However, it does mean that we should unwaveringly stand forth proclaiming the truth of God’s word despite man's disapproval. The Lord delivered these truths to us and for us and we should not allow the world to attack them unopposed. We must determine to take a bold stand! We must contend! No matter the repercussions, our allegiance to the One who graciously delivered such truths should shine forth as a light in a dark world.
