This passage provides some of the last recorded words from Paul to Timothy. In it, Paul charged Timothy to “preach the word” (2 Timothy 4:2), “watch thou in all things, endure afflictions,” and “make full proof” of his ministry (2 Timothy 4:5). Paul then focused Timothy’s attention toward Paul’s departure from this world. The three statements in 2 Timothy 4:7 point to Paul’s life of diligence. Paul had fought the fight, finished his course, and kept the faith. He certainly could be viewed by none as a lazy man. In fact, Paul was far from slothful, warning others day and night (Acts 20:31). Before salvation, Paul worked hard to destroy Christians and Christianity. After he learned the truth, he determined to give his best to the Lord and His work.
Doing the right thing is always the right thing to do and yields great benefits. For instance, consider what the Bible has to say about diligence. God’s word promises that diligence brings an increase of substance (Proverbs 10:4; Proverbs 13:4; Proverbs 21:5) and promotion (Proverbs 12:24; Proverbs 22:29). In other words, as the saying goes, hard work pays off. It is not difficult to prove that these benefits manifest themselves in the lives of God’s people who are diligent. Joseph and Daniel are two great examples of those who were diligent and their diligence brought them obvious promotion. Abraham and Job are great examples of diligent men who experienced a great increase of substance. A word of caution might be appropriate here. Men are not to be diligent merely for the sake of reaping its inherent benefits, but should be diligent for the sake of the One who called them to be diligent.
