Read Psalms 90:4  Yesterday we saw that God is eternal and outside of time.  That is very confusing to us.  We can't wait for tomorrow to come, but we have to.  But God doesn't have to wait - He is in tomorrow and yesterday and today - all at the same time!  Only He could do that because He is God!  Our verse today says that a thousand years is just like yesterday to God!  The verse goes on to say that for God, the thousand years are just like a watch in the night.  During King David's time, the soldiers would stand guard in the night.  They took two hours each, so there were 6 watches each night.  One soldier would stand guard for his two hours and then he would come and wake up the next soldier to stand his guard.  Then the first one could go to sleep safely, because his friend was standing guard over all of the soldiers.  The next morning, they would all wake up and march on to the next camp.  But when there weren't too many soldiers in a camp, they might have to stand guard a couple of times in the same night.  The first soldier would stand guard for his two hours and then would wake his friend up to take the next watch, and then he would go to sleep.  But after two hours, this second guard would wake up the first soldier and then he would get a couple of hours of sleep.  But when this first soldier would be awakened by his friend, it would seem like just a brief moment that he had been sleeping.  That is what the second half of our verse says about the thousand years to God.  The thousand years to God they were just like the brief nap that the first guard had before his friend woke him up.  To God a thousand years is a brief time, but to us it is a loooooong time!  Aren't you glad that God is eternal?  Isn't it great to be able to depend upon Him?
