Unfortunately, some Christians have become convinced that old age serves as a sufficient excuse for a lack of service to the Lord’s work. Granted, the field of one’s service may change, but there should always remain a willingness to serve. For instance, Moses received his initial call to deliver Israel at forty years old (Acts 7:23) but did not lead God’s people out of Egypt until he was eighty (Exodus 7:7). When he died at 120 years of age, he remarked that “his eye was not dim, nor his natural force abated” (Deuteronomy 34:7). At forty years of age, Caleb received a promise from Moses concerning the possession of land in Canaan (Joshua 14:7-9). Forty-five years later, Caleb took possession by driving out the mighty Anakims (Joshua 14:10-12). Caleb did something in his old age that many of the young men could not or would not attempt (Joshua 17:13).
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 these two groups becomes viewed as simply burdensome, both will cease to effectively attain God’s intended desire for society. The aged members of society are most 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). God purposed for the aged to instruct the young in practical and spiritual matters (Titus 2:1-11). While the young should feed off of the wisdom of the aged, the elderly members of society can be nourished by the joy, strength, and life of younger people (Ruth 4:15).
The Lord desired a special relationship with the nation of Israel choosing to bless them both spiritually and physically above all other nations. One such blessing involved bringing them safely into the land of Canaan. However, many of these blessings were dependent upon Israel maintaining the right type of relationship with the Lord. He, therefore, issued several commandments for the Israelites to carefully keep (i.e., Deuteronomy chapter 11). The Lord desired for Israel to “hearken diligently” (Deuteronomy 11:13) and “diligently keep” (Deuteronomy 11:22) these commandments. He wanted His people to carefully listen when He spoke, giving God their full attention (listening to every word). He also wanted them to attentively obey what they heard. He always desired for His people to listen to and obey Him. God speaks today through the Bible. He still wants men to diligently hear and obey.
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.
