You realize that if a homeowner had known at what time of the night a thief was coming, he would have stayed awake. He would not have let the thief break into his house.
Therefore, be alert, because you don’t know when the owner of the house will return. It could be in the evening or at midnight or at dawn or in the morning.
Jesus saw that they were in a lot of trouble as they rowed, because they were going against the wind. Between three and six o’clock in the morning, he came to them. He was walking on the sea. He wanted to pass by them.
“See, I am coming like a thief. Blessed is the one who remains alert and doesn’t lose his clothes. He will not have to go naked and let others see his shame.”
So remember what you received and heard. Obey, and change the way you think and act. If you’re not alert, I’ll come like a thief. You don’t know when I will come.
