Many years ago, I had a supertachycardia. I was in the ambulance and they had to shut my heart down twice. First one for 3 seconds and second time for 9 seconds.
I vivively remember the second time. I was present, but not present. My body felt like I was floating to the ceiling of the ambulance straps. It was a like a fireworks show, quiet and then floating. Suddenly, they restarted my heart and I was breathing as hard as I ever had trying to suck oxygen through the mask.
When we finally arrived at the hospital, it had returned to normal. There was about 15 people in my hospital room with a crash cart. Doc said I was lucky. If the second shot of adenocart didn't work, they would have paddle me while I was awake.
Make a long story short, my fear of death was gone. I am a long time believer too. Folks may think that Jesus is BS, but I would rather believe now, then do nothing and find out later the Bible is true and so is Jesus.
