And when he was demanded of the Pharisees, when the kingdom of God should come, he answered them and said, the kingdom of God cometh not with observation: Luke 17:20
I heard the joke from a friend first. "Ya wanna see the fastest draw in the west?" I did. His hand was poised over an imaginary gun. It never moved. Then he said, "Ya wanna see it again?"
Scoffers like to cite the scripture of the coming of Jesus. Some people say that He returned spiritually at Pentecost, but that was the Holy Spirit.
Then there is the idea that the words "not with observation" means the Lord will return invisibly. That is very popular. But lightning is not invisible. Neither will be His return.
But it will be quick. That He said. If He had said His return would be soon, the scoffers would seize on that. Almost two thousand years is not soon.
But,like lightning, His return will be quick. The Scoffers won't know what hit 'em.
For as lightning cometh out of the east, and shineth even to the west; so shall also the coming of the Son of man be. Matthew 24:27
