This life offers only a window of time and opportunity to work for the Lord. Youthfulness and old age both offer their own hindrances to service. In many ways, though not entirely, youth should be spent in learning, middle age in doing, and old age in teaching those who are learning and doing. Many of the greatest servants of the Lord found in scripture began their journey in youth by learning of the Lord and His ways (1 Kings 18:12; Psalm 71:5; 2 Chronicles 34:3; Job 29:4; Ecclesiastes 12:1). As they approached the prime of life, they invested their learning by serving the Lord (Numbers 8:24-25). As they passed their prime, they would pass their knowledge on to the next generation in hopes of the Lord’s work continuing and flourishing (2 Timothy 4:1-8)..
From youth, man is gripped by sin’s attraction. As he ages, the source of temptation may vary, but the fact that he is tempted remains constant. Paul instructed young Timothy to “flee . . . youthful lusts” (2 Timothy 2:22), yet Solomon’s heart was turned after other gods when he “was old” (1 Kings 11:4). Many believers have wasted the precious years of youth by succumbing to the youthful lusts of which Paul warned Timothy. Others have fought the good fight in their youth, only to regretfully compromise in their waning years. There is no time or age for the believer to be at ease concerning sin. Sin can be pleasurable but is always deceptive with uncertain outcomes for those who indulge.
Timothy was a young man who had been nourished up on the pure words of God since childhood (2 Timothy 3:15). His mother and grandmother invested the necessary time to teach him about good and bad, right and wrong. This early development helped him to understand the importance of purity (2 Timothy 1:5). Because these two women brought him up in the nurture and admonition of the Lord, Timothy had been shielded from much of the wickedness and filth to which others were exposed. With this upbringing in mind, Paul called upon Timothy to be an example in purity. Paul stressed the importance of Timothy maintaining his purity so that other believers might be able to see his life and follow in his example.
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.
From the Old Testament to the New Testament, many things change; however, some themes remain constant. One such theme involves the Lord's desire to use pure things and pure people. God commanded His people in the Old Testament to make sure the things used in the tabernacle were purified (Leviticus 8:15). He also commanded that His servants be purified (Ezra 6:20). In the New Testament, the apostle Paul confirmed the continuation of this theme by saying that “pureness” approved him as a minister of God (2 Corinthians 6:4-6). God still requires those who serve to strive to live pure and holy lives. Impurities hinder the Lord’s effectiveness in our lives though we may not be aware of the hindrance.
