Age Does Not Equal Wisdom - Ecclesiastes 4:13
Wisdom often comes through time and experience. It should not, however, be assumed that old age equals wisdom. The Bible says, "Better is . . . a wise child than an old and foolish king . . . ." Wisdom comes from the Lord, and in distribution of wisdom, He is no respecter of age. Perhaps the wisest statements given by man in the Book of Job were given by a young man named Elihu (Job 32:6). He listened carefully as Job's older friends spewed their foolishness. He thought that "days should speak, and multitude of years should teach wisdom" (Job 32:7). Eventually, he came to the conclusion, "great men are not always wise: neither do the aged understand judgment" (Job 32:9).
Christ, Sacrificed for Us - 1 Corinthians 5:7
God demands righteousness, and when His demands are not met, He calls for the shedding of blood for the remission of sins (Hebrews 9:22). Throughout the Old Testament, sacrifices majored on the blood of animals, but they could never take away sins (Hebrews 10:4). God, in mercy, sent His Son to give "himself for us an offering and a sacrifice to God for a sweetsmelling savour" (Ephesians 5:2). Unlike the Old Testament sacrifices, the Lord Jesus was a onetime sacrifice that offered forgiveness of sin for all. In shedding His blood, the Lord Jesus Christ became man's sacrifice, and man need look no further than the shed blood of Christ for a means by which God is satisfied.
Let No Man Despise Thy Youth - 1 Timothy 4:12
Respect is not inherited; it is earned. When writing to young Timothy, Paul admonished him to "let no man despise" his youth. In other words, Timothy was responsible for how others handled his youth. Paul's advice for Timothy was for him to be an example to other believers in every facet of life. If he did that, no man would despise his youth. They would begin to see Timothy as a man and would have no trouble following his leadership. In the beginning, David was disdained because of his youth (1 Samuel 17:33, 42), but when he defeated Goliath and gave Israel the victory, he was given the respect of a hero of war. David did not show up expecting respect, he earned it by his actions.
Rejoice in Each Day - Ecclesiastes 11:9-10
Many people fail to enjoy the present blessings worrying about the possibility of future difficulties. Though each time of life is certainly filled with its difficulties, it is also filled with tremendous opportunities for blessing. When young, a person ought to rejoice in his youth while keeping in mind that God will bring his deeds into judgment. When growing older, people ought to rejoice in getting married, having children, working, and serving the Lord. As one grows older, he can enjoy the benefits of each phase of life knowing that God has special blessings in store for each day. There is no need to miss today's joys worrying about troubles and sorrows that may never come.
A Window of Time to Serve - Acts 13:36
This life offers only a window of time to work for the Lord. Youth 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. 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 put their learning to use 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 the work of God would go on (2 Timothy 4:1-8).
All Have Something to Offer - Deuteronomy 32:7
The strength of any people will be determined by how they deal with two people groups: their young and their old. If at any point, either of the two groups becomes a burden, both groups will cease to prosper. The aged members of society are often its wisest. They have had successes and failures and learned from both (Deuteronomy 32:7). They have witnessed the Lord's provision through difficult times (Psalm 37:25). They can instruct the young in practical and spiritual matters (Titus 2). But just as the young feed off of the wisdom of the aged, the older members of society can be nourished by the joy, strength, and life of younger people (Ruth 4:15).
Why Christians Fail to Witness - Romans 1:16
When asked, the average believer may offer up several "reasons" why it is not feasible for him or her to tell others about the need for salvation. These reasons often seem spiritual in nature and are often accompanied by verses of scripture for support. However, the real truth is that believers who do not witness fail to do so because they are ashamed. Immediately, believers who refuse to witness will be offended by this statement, but the apostle Paul confirms its validity. The reason Paul was "ready to preach the gospel" to those who were at Rome was because he was "not ashamed of the gospel of Christ." Why was he not ashamed? Because he knew that it was "the power of God unto salvation."
The Fear of Growing Old - Psalm 71:18
Many people suffer from gerascophobia or the fear of growing old. Perhaps ultimately it is a fear of death, but other conditions exist in old age that cause people to fret. One of these concerns was expressed by the penman of Psalm 71. On two different occasions he requested that the Lord would not forsake him when he was old and grayheaded (Psalm 71:9, 18). The Lord knew the fears of man and promised, "even to your old age . . . and even to the hoar hairs will I carry you: I have made, and I will bear; even I will carry, and will deliver you" (Isaiah 46:4). Growing old is a blessing, in fact, it is one of the greatest blessings the Jewish people will experience in the kingdom (Zechariah 8:4).
Sin Cares Not for Your Age - Genesis 8:21
From youth, man is bent toward sin. As he ages, the source of his temptations may change, but the fact that he is tempted does not. 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). A man's youthful strengths may become his downfall in latter years. Many believers have wasted precious years of youth by succumbing to the youthful lusts of which Paul warned Timothy, while others have fought the good fight in their youth, only to compromise later in life. There is no time or age for the believer to be at ease concerning sin.
Glory and Beauty - Proverbs 20:29
Each phase of life bears the marks of certain strengths and weaknesses. In youth, man has a great amount of zeal. In fact, "the glory of young men is their strength." He might accomplish great things, but his lack of knowledge limits his ability to accomplish greatness. As time passes, man learns from his failures and successes. He obtains knowledge and enjoys wisdom that eluded him in his youth. His glory is no longer his strength, but his beauty is now "the gray head." The very thing that limited his ability to accomplish great things in his youth is now a virtue he knows, but the glory of his youth has departed. He has the knowledge, but he lacks the strength.
