Matthew 24:27, “For as the lightning comes from the east and shines as far as the west, so will be the coming of the Son of Man.”
Consider the character of lightning in a thunderstorm. Can you ever rightly predict its movements and strikes? You cannot; it is impossible. When someone is struck by lightning, she never sees it coming. The coming of Christ is just as unpredictable, and we are powerless to do anything about it. “We can wear no metal,” you might say. Indeed, yet I know some who were struck by lightning without any metal nearby or on their person! We cannot predict the coming of Christ, and we are powerless to do anything about it. We can only wait for its inevitability.
Yet some are foolish enough to think we can predict His coming. Christ has warned us of these false christs and false prophets. Some will say, “There he is!” and others, “He’s coming on this day” (vv. 23-24)! They are wrong every time, yet they persist and even deceive the elect when possible. But Christ will come as unpredictable and unexpected as a flash of lightning. I could be preaching from the pulpit, sleeping in bed, driving on the road, or even be on the toilet, and Christ could come at any moment. (Well, I hope He doesn’t come whilst I’m on the toilet. That would be awkward.) Therefore, we wait expectantly on His arrival. In our suffering and joys we pray, “Come, Lord Jesus.” Indeed, He comes in His Spirit, but in it we also pray that He come quickly like lightning to deliver us from all sin and evil.
