I grew up in a military family, and during the Cuban Missile Project we were stationed in Fort Rucker, a military installation in South Alabama. I remember my dad being put on watch. For days at a time he would disappear, coming home only for a short hour or two before he resumed his battle station. For period of two months this hyper-vigilance continued. Why? Watchmen were needed to be prepared. And in our scripture verse for today, Jesus commands us to be watchful and prepared for the coming of the Lord. And to make sure that when He returns that you are his ally and not His enemy!
Therefore, keep watch, because you do not know on what day your Lord will come.
