Personally I don’t think Christ will come back in my lifetime. Like somebody else here, I’m 55 and if some earlier things I’ve experienced are correct, I expect to peg out in my 70’s sometime.
I also believe God intends to drive the human race off the planet. He’s allowed us to get so far as space research, space medicine, moon landings, and to develop the associated technology (very rapidly incidentally - it took 1900 years from Christ to learn to fly and just 106 years later supersonic flight, rocketry, satellites, space shuttles, and space stations are taken for granted)… We have robotics, computers and are just starting to dabble in quantum teleportation, which in my opinion will lead to personal teleportation down the track, hence the ability to move rapidly enough to make it possible.
BUT … I expect a lot of trouble in the meantime, which will set the scene for a planet so badly damaged that we will have to move off it if we’re to have any sort of decent lifestyle. Both the ancient book of Revelation and recent Marian apparitions give dire warnings. So much so that a lot of people will think Christ is going to come back, as the Rapturists do, and I think they’re badly mistaken.
I don’t think He’ll come back in the near future. After all one of His other comments was that He’ll return at an hour when we don’t expect HIm to come back. But like everybody else here however, my opinion is conjecture since we just don’t know. Even Christ didn’t know, as He made clear.
