What does the Bible mean when it says to “have no fellowship with the unfruitful works of darkness”? Does this mean that believers should never speak to those who do not know Christ as Saviour? The key involves understanding Bible terminology. The word fellowship is a two part compound word. A simple Bible study of the root word fellow indicates that it involves two people working as one (John 11:16; 3 John 8); therefore fellowship involves two people being closely associated. The command for believers to avoid close association with unbelievers is further confirmed when the Bible says believers and unbelievers should not be “unequally yoked together” (2 Corinthians 6:14). When two people are yoked together, they are united in work; but the saved should never unite with the lost in such matters. More importantly, believers must never yoke up with unbelievers in God’s work (Ezra 4:3).
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).
