Have you ever stopped to think that today is the smallest division of God-given time?  Seconds, minutes, hours are artificial, man-made time divisions, but the period of time from dawn to dusk is the shortest division of time on God's clock.  Time is a strange thing in itself.  It is something like fence posts or telephone poles you pass as you drive down the highway, but like a fence it encloses our lives, and between the two poles of life and death we are very much prisoners of time.
