As for man, his days are as grass: As a flower of the field, so he flourisheth. 16  For the wind passeth over it, and it is gone; And the place thereof shall know it no more. Psalms 103:15-16 

The Bible says that our life is short. It compares it to grass or a flower. It springs up quickly but before long it is gone. It disappears quickly. It is so short that many times we do not even remember it was there. Our life is short. What are we going to do with it? Are we going to serve God? Are we going to spend our life living for him?
