The knowledge of something wrong helps a spiritual person avoid such activity. On the surface, one might fail to distinguish much of a difference between the fruit of knowledge and charity in today’s passage. Both evidently build up the believer. Yet, a closer look reveals the major difference. The Bible says that knowledge “puffeth up.” The idea is that knowledge makes one feel superior and can offer a false strength. Knowledge seems to do the same work as charity, but knowledge without the charity serves as a façade. Charity, however, offers real growth and stability. Unlike knowledge, charity edifieth. Charity not only builds up the believer but also those who associate with that believer. The only way to be edified and the only way to edify others involves seeking the Lord for pure, unadulterated charity.
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.
