Why is it important for Christians to number their days?

Numbering our days is crucial for Christians as it brings about an awareness of life's brevity and provides perspective in the face of earthly challenges. Moses' prayer in Psalm 90 reveals that realizing our time is limited urges believers to seek divine wisdom actively. Acknowledging that our lives are but a vapor helps us to prioritize spiritual growth and kingdom work. This practice is not merely an exercise in counting; it is a vital reflection on how we use the time given by God, ultimately leading us to rely more on His grace and guidance.
