Truth is a crucial piece in the believer’s armour, girding the loins and, as such, freeing a man from life's entanglements.
When men choose to reject the truth, God tends to withhold further truth from them. The result is spiritual and intellectual darkness.
God is "a God of truth" and the words that proceed forth from Him reflect His nature. As such, the words of God are just as true as the God of the words.
Men could know the truth if they desired to know it. Sadly, most men refuse to pursue and know the truth made so readily available unto them.
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.
A godly mother and grandmother helped raise Timothy by teaching him the truths of God’s word (2 Timothy 1:5; 2 Timothy 3:15). Paul wrote to Timothy specifically warning him in 1 Timothy chapter 4 concerning the dangers of the last days (i.e., the doctrines of devils, fables, and unedifying quarrels). In the midst of these warnings, Paul reminded Timothy to take heed unto himself. Timothy needed to guard against troubles from without while diligently taking care of his own walk with Christ. The Old Testament further reinforces these truths. The children of Israel were told to keep their souls diligently (Deuteronomy 4:9) and Solomon instructed his son to keep his heart “with all diligence” (Proverbs 4:23). Every Christian should carefully and zealously guard his walk with the Lord.
