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).
Why do people murmur? What causes them to get so frustrated to the point where they would publicly discuss their disappointment with their circumstances? The Bible provides several reasons. In Jude 16, the Bible says that people complain or murmur because they are “walking after their own lusts.” In John chapter 6, the Lord Jesus indicated another reason why an individual might complain. When the Lord knew that His disciples murmured within themselves, He asked them if they were offended (John 6:61). In other words, people murmur when things turn out differently than they had hoped. It is not so much the trial that bothers them but the offense to their self-will.
The Lord detests murmuring. He hates it so much that He sent fire among the Israelites because of their murmurings (Numbers 11:1). In the New Testament, He warned believers to avoid falling prey to the same sin as the Israelites (1 Corinthians 10:1-14). Additionally, New Testament believers are admonished to do all things without murmurings (Philippians 2:14-16). People murmur as they focus on events within their lives rather than upon the Lord and His word. Yet, the Christian’s life events are ultimately brought to pass, either directly or indirectly, by a loving and caring God. The Lord abhors murmuring because it directly insults His working and provision in our lives.
