The Lord, in His omniscience, has provided man with everything he needs through salvation and the grace that brings salvation. One might ask, “How does salvation teach sobriety?” A proper understanding of grace and salvation reminds man that he is completely inadequate in and of himself. Apart from the Lord’s intervention, man would be on a slippery slope towards the pits of hell. In his very best state, man’s righteous acts are no better than filthy rags (Isaiah 64:6). When a man meditates upon his salvation and the grace of God that gave him salvation, he avoids the snare of pride. He knows full well who he is and what God had to do to make him fit for heaven. He knows he owes the Lord a great debt and determines to be alert in his daily walk.
Most people unfortunately limit the meaning of sobriety to the absence of alcohol, but scripturally speaking, the meaning involves a much broader scope. Sobriety is the opposite of being beside oneself (2 Corinthians 5:13) or mad (Acts 26:25) and is akin to being alert (1 Thessalonians 5:6). The word sober is used in conjunction with the words grave (1 Timothy 3:11; Titus 2:2) and temperate (Titus 1:8; Titus 2:2) indicating that it is accomplished when one is in control, down to earth, and finds the proper balance in his thoughts and actions. One who is sober is humble (Romans 12:3), not drunken (1 Thessalonians 5:7-8), and well aware of the circumstances surrounding him at all times (1 Thessalonians 5:6, 8; 1 Peter 5:8).
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.
