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)..
When men follow after vanity, they themselves become vain. An individual must make a conscious decision to turn from walking after the Lord to pursue vanity (Jeremiah 2:5). Those who follow after vanity are void of understanding (Proverbs 12:11) and end up in poverty (Proverbs 28:19), sometimes both spiritually and physically. David expressed his concern in this area when he said, “I have not sat with vain persons” (Psalm 26:4). He knew the danger of following vanity and declared that he refused even to sit with vain persons. In Psalm 119:37, the penman pleaded with the Lord for help in turning away his eyes from beholding vanity. God desires and wills for the saints of God to cease from following after vanity.
The Lord redeemed Israel out of Egypt for the purpose of worshipping Him. Instead of willingly serving Him, the nation of Israel turned to vanities. In doing so, they ignited the fire of God’s anger (Deuteronomy 32:21-22). Ultimately, God chose to provoke Israel to jealousy with a people “which are not a people” – the Gentiles. Since Israel had provoked the Lord to anger with their vanities, He was going to use Gentiles, whom Israel knew to be “not a people,” to provoke Israel to anger. The Lord expects the redeemed to flee vanity and give themselves wholly to His work, worship, and will. The Lord has now redeemed Jew and Gentile “for his name” (Acts 15:14), and He expects the same from each of us.
