And yet we ought to live with such an attitude. There are many in this world who have excellent health, who see no signs of approaching death, and yet will die this very day. They know nothing of their fast approaching death and probably are thinking nothing about it. However, this makes no difference for them. The sands of their time are about to run out.
Time is precious because once lost, it can never be recovered.
There are many things that if we lose for a time, we can regain later. Time is not one of them. When a moment of time is gone, it is gone forever. The parts of our time that are gone can never be recovered. The encouragement in all this is that we have a new day before us.
