Did you miss the time that Rome descended from God out of heaven?
Drat! Yeah, I missed that one.
What I didn't miss was my friend and I dropping acid on the bridge over the Tiber.
(Not advocating its use.)
Almost immediately, up drives a van and out of it, with his entourage, steps an Indian Guru with flowing white robes. They took us on a drive around Rome and then to his Ashram. He was Swami Paramahansa Yogananda's successor(Kriya Yoga). I don't think he was a disciple of Christ. I got his address and we went back weeks later but he had returned to India.
After we left there, we tried to get to an Elton John concert. This was 1971 and we didn't even know who Elton John was, but we'd heard there was a rock concert in Rome.
We kept getting on the wrong bus and wound up riding the wrong buses all day until finally we caught the last bus to the Youth Hostel as it got dark. It had been fun though. We'd sit in the back of the bus and when the bus would hit the deep swags in the street the bus would throw us up to the ceiling. Yep.... did that all day. We must have passed the Colosseum a dozen times. I remember seein' it go by. Actually, we were going by.
The next day , we caught the train for a 12 hour return trip to Sicily.
I don't think it was the New Jerusalem but I've learned to be open to consider evidence from others on such matters.
PS: I was genuinely saved by the Lord Jesus Christ according to His gospel of grace in 1979 and renounced much of that which I described.
It's a dead end.
