Seek the LORD while he may be found; call on him while he is near.—Isaiah 55:6
Time is the enemy of teachers, speakers and preachers—we are always battling with the clock. In the context of formal church services, this battle goes back to the so-called olden days when preachers walked up and took their place behind the pulpit. At the beginning of the sermon an hour glass of sand was turned on its end. The passing of time was determined as small quantities of sand passed from the upper chamber, which at the beginning of the hour was full, to the lower chamber.
When the last grains of sand filtered through the hour glass into the lower chamber, the sermon was finished. Or not, in some cases! But, preachers were on notice—those who consistently ignored the passage of time did so at their own risk.
