Believers are not to speak, look, think, or act like the world. In every way possible, believers are to remain separate and distinct. Believers saved for any length of time have noticed the drastic shift in what the world defines as acceptable and unacceptable behaviour. For instance, man in general once disdained the idea of tattoos, body piercings, and cuttings in the flesh (Leviticus 19:28). Yet, now these things are not only acceptable but even practiced by believers. The world used to distinguish between men and women, even taking note of one’s hair length (1 Corinthians 11:14-15). Yet these distinctions have been blurred and in some cases eliminated with men attempting to become women and women men. The people of God are not to follow along with cultural shifts, but abide rather in the unchangeable words of God.
Believers should be zealous of good works, but their zeal must not spring from a position of ignorance. The Bible points to the Jews as a zealous people, but their zeal was not according to knowledge. Nobody worked harder trying to reach a righteous state than did the Jews. However, they failed to realize that true righteousness comes as an unmerited gift from God. Yet, the Jews were “ignorant of God's righteousness,” and went “about to establish their own righteousness” (Romans 10:3). Paul repeatedly testified concerning the futility of trying to earn God's favour through one’s own efforts (Acts 22:3; Philippians 3:6). Before Paul came to know Christ, he thought he should fight against Christ’s followers and zealously persecute the church of God. He even placed many of the new believers into prison and caused their deaths. Yet, he declared that all this was done in ignorance (1 Timothy 1:13). He, like the Jews, had a tremendous zeal, but that zeal was not according to knowledge.
