The Bible clearly points out that by God’s grace the apostle Paul laid the foundation which is Jesus Christ and Him crucified. All those who have come after the apostle Paul have built upon that foundation. It is with this in mind that Paul warned believers to take heed how they built upon the foundation. The foundation has been laid, and no other foundation can be laid, but each believer must carefully examine the means by which he builds upon Christ. Not only should believers take heed to their daily walk, but self-examination is also necessary in their manner of service for the Lord Jesus Christ. Each believer should search the scriptures to ensure that his efforts glorify the Lord. Far too much effort is self-serving and selfish and not God-centric. Self-examination helps define one’s motives.
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.
