When people don't learn from history or God, they're destined to repeat it again.
Whenever the real God's rejected, a lesser god steps in singing peaceful lulliby's like Lennon's to the world in hopes of hypnotizing to program people into a very dangerous spiritual condition leading to tyranny.
John Lennon's in eternal hell having rejected Jesus as Messiah and his spirit even today is going to likely bring multitudes there due to ignorance of God's Word through rebellion and stupidity.
