“No one knows about that day or hour, not even the angels in heaven, nor the Son, but only the Father. Be on guard! Be alert! You do not know when that time will come. It’s like a man going away: He leaves his house and puts his servants in charge, each with his assigned task, and tells the one at the door to keep watch. “Therefore keep watch because you do not know when the owner of the house will come back—whether in the evening, or at midnight, or when the rooster crows, or at dawn. If he comes suddenly, do not let him find you sleeping. What I say to you, I say to everyone: ‘Watch!’ ” - Mark 13:32–37
During my college years I worked for a security company. My responsibilities included traveling to all our locations every night to be certain our guards were doing their jobs. I lost count of how many times I found guards asleep at their desks, in their cars or somewhere in the building. I never kept the same schedule, so they never knew when I would arrive. I learned that it takes real effort to stay alert.
Jesus taught a great deal concerning his second coming, but he never pinpointed a set time. He simply left his disciples and all believers with a word of council: Be on guard! Be alert! Watch! He intended for us to stay on top of our game as we waited for his return. He doesn't want sleepers; he wants his followers showing real effort to stay alert.
You can study prophecy for years and still live like the Lord's return will be sometime in the next millennium. The Lord calls us to be spiritually on point. What are you doing to redeem the time for the Lord today? When the Lord returns will he find you showing real effort to stay alert?
