"Like an hourglass with a certain number of grains of sand within it, God has appointed your life to last only a certain number of days, and you have absolutely no idea how many there are.... In God's presence, consider: I have no idea when my life will end. All I know is that death will come for me eventually. Am I doing anything to prepare for the real possibility that God may call me, sooner rather than later? If he called me into eternity today, would I be ready?"
