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).
What does the Bible mean when it says to “have no fellowship with the unfruitful works of darkness”? Does this mean that believers should never speak to those who do not know Christ as Saviour? The key involves understanding Bible terminology. The word fellowship is a two part compound word. A simple Bible study of the root word fellow indicates that it involves two people working as one (John 11:16; 3 John 8); therefore fellowship involves two people being closely associated. The command for believers to avoid close association with unbelievers is further confirmed when the Bible says believers and unbelievers should not be “unequally yoked together” (2 Corinthians 6:14). When two people are yoked together, they are united in work; but the saved should never unite with the lost in such matters. More importantly, believers must never yoke up with unbelievers in God’s work (Ezra 4:3).
Separation is the outcome of separation! When a nation (i.e., Israel in the Old Testament) or an individual (i.e., a believer in the New Testament) is set apart by the Lord, that nation (or person) has become disassociated with the rest of the world. Moses made this point in Exodus 33:16 when he said, “For wherein shall it be known here that I and thy people have found grace in thy sight? is it not in that thou goest with us? so shall we be separated, I and thy people, from all the people that are upon the face of the earth.” Separation is not something accomplished through diligence but occurs naturally after a person comes to know Christ as Saviour. Christians who remain attached to the world find little satisfaction with the things of the world or less appeal for the things of God.
