When I was a young man I smoked pot and tried other illicit drugs. I actually OD'd on PCP/speed and was hospitilized for several days before recovering consciousness. I believe I all but died (maybe did die) in this incident. I remember entering heaven. I had on an oversized robe (it didn't fit yet because I wasn't ready for it)and was hooping and hollering that I had actually made it to heaven. People I knew told me I had to go back, it wasn't my time yet. I didn't want to leave, I didn't think I would ever make it back. An unknown young woman told me I had to go back. She got through to me and I said OK. It still took a couple of years before I gave my life completely to Christ. I have come to believe the unknown young woman was my daughter who was born years later and is now a lovely Christian young woman. I know this sounds kookish but I don't think all of this was some biomechanical response to oxygen deprivation/chemical halluicintion, etc. I think it was the mercy of the Living God.
It must have been so hard to return, but obviously our beautiful Lord has work for you to do.
