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).
There has never been, nor ever will be, a book like the Bible. Unfortunately, some people who desire to learn its contents simply take the wrong approach. It cannot be studied like a textbook or read like a magazine or novel. It must be approached prayerfully with the help of God’s Spirit with total dependence upon Him for illumination. According to today’s passage, an unsaved man cannot fully understand the word of God because he lacks the spiritual discernment necessary to grasp its full truths. No one can approach the Bible with a fleshly mindset; it must always be approached with faith, believing that it is truly God’s word. Only then can the student with the Spirit’s help rightly discern the things intended to be understood. An improper approach has led many people to believe the Bible, like all other books, contains contradictions and errors. God graciously affords man the necessary spiritual discernment increasing a man’s faith leading him to take God at His word. When man rejects discernment, he increases his darkness.
