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 detests murmuring. He hates it so much that He sent fire among the Israelites because of their murmurings (Numbers 11:1). In the New Testament, He warned believers to avoid falling prey to the same sin as the Israelites (1 Corinthians 10:1-14). Additionally, New Testament believers are admonished to do all things without murmurings (Philippians 2:14-16). People murmur as they focus on events within their lives rather than upon the Lord and His word. Yet, the Christian’s life events are ultimately brought to pass, either directly or indirectly, by a loving and caring God. The Lord abhors murmuring because it directly insults His working and provision in our lives.
