A Heart of Wisdom
After the wilderness wanderings, Moses used these images of the brevity of life in Psalm 90: “We have finished our years like a sigh” (v. 9) and “We fly away” (v. 10). We experience the same dilemma, wandering in the wilderness of routine and crowded schedules as the years race by. But there is a solution to this plight, and it is found in the pivotal verse in the psalm: “So teach us to number our days, that we may present to You a heart of wisdom” (v. 12). If we want to have wisdom, the skill in the art of living life with each area under the dominion of God, we must regularly remind ourselves that our days upon this earth are numbered. If we blind ourselves to this reality, our value systems will automatically be distorted and we will serve the wrong master.
If, like Moses, we want the work of our hands to have permanency (v. 17), we should daily remind ourselves that we are “aliens and strangers” (1 Peter 2:11) on this earth and that our true citizenship is in heaven (Philippians 3:20). Our own works quickly evaporate and are lost forever. But God is eternal (vv. 1-2), and His work abides. Therefore we must invest in that eternal work; His works done through us last forever.
Only two things on earth will go into eternity—God’s Word and people. God has placed us here to grow in Christ and to reproduce the life of Christ in others. Each of us has specific opportunities to do this in our own spheres of influence, and as we abide in Christ and let His words abide in us, we will bear lasting fruit (John 15:7-8), and the living God will confirm the work of our hands.
The great saints along the way learned the wisdom of having only two days on their calendars: “today” and “that day” (the day they would be with the Lord). If we want a heart of wisdom, we should learn to live each today in light of that day. When we daily remind ourselves of the real purpose for our sojourn on earth, we will cultivate an eternal perspective that influences all our work and all our relationships. In 2 Corinthians 4:16-18, Paul summarized the vision that determined the course of his life:
Therefore we do not lose heart, but though our outer man is decaying, yet our inner man is being renewed day by day. For momentary, light affliction is producing for us an eternal weight of glory far beyond all comparison, while we look not at the things which are seen, but at the things which are not seen; for the things which are seen are temporal, but the things which are not seen are eternal.
