I usually prepare and read a eulogy or history of the deceased when I conduct a funeral. Our days seem to go by slowly, but really they go by quickly. These verses all relate the importance of numbering our days because time is deceptive. Because of the value of time 1. There is only a limited amount of it for all of us.
Time is limited and that makes it valuable.
Better pray to God for wisdom. In a church I pastored, we took a survey to discover how many hours per day the average adult could decide to use as he wanted. Taking into account work time, meal time, travel time, etc., we discovered the working adult only had five hours per day he could really use any way he wanted. It can only be used once. There are only 1,440 minutes in a day.
