After the Rapture happens, the true biblical explanation for what just had happened will be soundly rejected, but in time many will turn to Israel's long rejected Messiah (Jesus) and will begin to understand that it was the Rapture. But for most after the Rapture, a counterfeit explanation for this event will be put forth and pushed by the media. If one rejects the Bible, the only logical explanation for what happened will be that aliens had removed some of the inhabitants of earth.
The "UFO deception" is therefore part of our culture as the world approaches the Rapture. What are these craft that appear definitely to be real and defy the laws of physics? Right now beats me! But for those of us to be leaving in the Rapture, let's ask the Lord when we are home with Him, and I believe He will give us insight as to the truth of these objects flying around in our atmosphere.
