The Bible often speaks of sin as a thing of the past pertaining to the believer’s life prior to salvation. This is not because believers are without sin, but the goal of every believer should be to depart from and avoid the sins which once controlled his life prior to salvation. These past actions which helped us to see our lost condition should be viewed as the friend of our past and the enemy of our present and future. This is exactly how Paul spoke of envy in his epistle to Titus. According to Paul, “we . . . were sometimes foolish, disobedient, deceived, serving divers lusts and pleasures, living in malice and envy, hateful, and hating one another.” Concerning the sins of the past, Paul further admonishes: “let it not be once named among you, as becometh saints” (Ephesians 5:3).
The importance of fellowship cannot be underestimated, but neither can the importance of refusing to fellowship. It is important to fellowship with the right people, but also equally important that we “have no fellowship with the unfruitful works of darkness.” The people of God have no business yoking together with the world in any work of God no matter how beneficial the help might seem. Fellowship suggests an agreement amongst the involved parties. Yet, 2 Corinthians 6:14 drives home the point when it says, “Be ye not unequally yoked together with unbelievers: for what fellowship hath righteousness with unrighteousness? and what communion hath light with darkness?” When we fellowship with carnal believers or the unsaved, we accept their motives and objectives as our own.
