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” (verse 9) and “we fly away” (verse 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” (verse 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 (Psalm 90:17), 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, and His work—including the work He does through us—lasts forever.
