How does Psalm 90 teach us to number our days?

In Psalm 90:12, Moses implores God to 'teach us to number our days that we may get a heart of wisdom.' This request signifies the importance of recognizing the fleeting nature of human life and the need to live purposefully. By numbering our days, we are encouraged to reflect on how we spend our time, prioritize our relationship with God, and strive for wisdom in our actions. This concept aligns with historic Reformed theology, which emphasizes the importance of living a life that glorifies God and directs our focus toward eternal matters rather than temporal concerns.
