I’ve become increasingly interested in near death experiences, and the ones that interest me most are those involving atheists. Here is one of the more well-known accounts by a former atheist, Howard Storm, who was an art professor at Northern Kentucky University when he had his experience in 1985 while awaiting surgery for an intestinal problem. As he lost consciousness, Storm reports that he exited his body and had a distressing, hellish encounter with malevolent beings, who essentially tortured him. In his agony and desperation, despite his atheism, he called out to Jesus to save him. According to Storm, Jesus did just this, rescuing him from the tormenting beings and eventually introducing him to some other spiritual beings (angels?), who guided him through an intense life review and with whom Storm says he had a lengthy conversation. The whole experience was recorded by Storm and published in his subsequent book, My Descent into Death.
After his NDE, Storm was a changed man. Prior to the experience, he was a confirmed atheist, but afterward he could not stop talking about God and the Bible. Storm eventually resigned from his teaching position and attended seminary to become a Christian minister. Today he pastors a church in Ohio and does a lot of painting.
