If each of us knew how much time we had left in this lifetime, we would live it differently. Life is really short in the light of eternity. In Psalm 39:4 David cries out to God and says, “Show me, O Lord, my life’s end and the number of my days; let me know how fleeting is my life. David acknowledged how fleeting our time is and how quickly it will all end. We are not promised tomorrow, so we need to make sure we make the most of today and every day.
