Did you see this news item?
Long story short, I have always been very skeptical about people claiming to have visited Heaven (because as James Mitchell once said, “Once you’re there….you’re there! permanently/happily) especially when the stories told contradict biblical truth and/or encourage believers to look for spiritual truth in extra-biblical sources.
On the other hand I do believe there is some legitimate and amazing validation of the reality of life after death, if/when one does the work to analyzing with a forensic and a biblical lens the hard data of NDEs (Near Death Experiences).
I’ve done messages on that subject in the past and promise to do so again sometime fairly soon.
