Paul served as Timothy’s mentor. In fact, Paul referred to Timothy as his “son in the faith” (1 Timothy 1:2). As Timothy’s mentor, Paul gave Timothy truths with the intent that he would pass along those teachings to other believers. Though there are certainly variations of what should be taught, Paul laid out two foundational categories when he mentioned “words of faith and of good doctrine” (1 Timothy 4:6). Though specifics are given in the epistles of First and Second Timothy and Titus, every teaching should reflect the categories set forth by the apostle Paul. Even practical teaching ought to be based upon the words of God, as some teachings are good (2 Thessalonians 2:15), and some are bad (Matthew 15:9). Every teacher should teach with hopes of eventually learning from his students when they too become the teachers.
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.
Believers should seek to be pure in every facet of life. One might consider limiting this to the places he goes or the things he hears and sees, but purity demands a much greater focus. Believers ought to think on pure things (Philippians 4:8) with pure minds (2 Peter 3:1) and pure consciences (1 Timothy 3:9; 2 Timothy 1:3). In particular, believers should have pure hearts before the Lord (1 Timothy 1:5; 2 Timothy 2:22). A pure heart will lead to a pure conscience and a pure mind. A pure heart changes where a man goes, what he looks upon, and the things he allows to enter into his ears. Every Christian should strive to make sure that all things are pure.
