Has anyone had a vision of Heaven during a church service? I was near the altar during the Revelation Song and I hit my knees to the floor. Talking to God in English & in tongues, with tremblling, weeping and shaking. Next thing happened, clear like fumes surrounded me, like propane or a gas. Somebody told me later, it was the glory cloud. The whole sky opened up in front of me for 4 seconds. I saw the sea of glass, the new city, the precious stones. It was a mile high and a mile down, like a Grand Canyon of ice and glass. I went to the pastor and we talked for an hour. I never knew what a vision was until I had one.
