Why is it important for Christians to number their days?

Psalm 90:12 offers a profound insight into the importance of numbering our days, as it is a means to gain a heart of wisdom. By recognizing the brevity of life and acknowledging that our time on earth is limited, we are prompted to make wise choices that align with God's purposes. This act of counting our days helps us to prioritize our spiritual well-being over mundane pursuits and encourages us to live in a manner that glorifies God. Moreover, it instills in us a sense of urgency to share the gospel and invest in eternal matters, understanding that the impact of our earthly deeds extends beyond our temporary existence.
