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 the outcome of separation! When a nation (i.e., Israel in the Old Testament) or an individual (i.e., a believer in the New Testament) is set apart by the Lord, that nation (or person) has become disassociated with the rest of the world. Moses made this point in Exodus 33:16 when he said, “For wherein shall it be known here that I and thy people have found grace in thy sight? is it not in that thou goest with us? so shall we be separated, I and thy people, from all the people that are upon the face of the earth.” Separation is not something accomplished through diligence but occurs naturally after a person comes to know Christ as Saviour. Christians who remain attached to the world find little satisfaction with the things of the world or less appeal for the things of God.
A slothful man hunts and even makes a kill but considers it too much work to prepare and roast that which he killed. He would rather see the meat go to waste than to put forth the effort necessary to preserve the food. However, a diligent man considers his substance to be precious. He has no desire to see something go to waste. Interestingly enough, the Lord Jesus made a point along these lines at the feeding of the five thousand. After He fed the multitude, the Lord Jesus told the disciples to “Gather up the fragments that remain[ed], that nothing be lost” (John 6:12). It was important to the Lord that His followers made full use of the substance given to them of the Father. Nothing was to go to waste. A diligent man considers every part to be precious, even those things the world would allow to spoil.
