Well...not really. We know that the devil is capable of doing all sorts of things to deceive people and draw them away from the Gospel.
The apparition contradicted God’s word by telling him he could do no wrong. By his own admission, he was a Christian more in name than in belief. How do you make it to heaven without belief, being born again?
I didn’t read the book, only watched him in interview
But the implication of the experience he described was that she (his spirit guide who turned out to be his birth sister he had never seen or met or even knew about) was telling him that where he was now with her (in “heaven”), there was no longer anything he could do wrong, and he had nothing to fear
I would not get too hung up on whether other people are “good enough” Christians to get to heaven- there are plenty of NDEs by ordinary people of many faiths and beliefs and no faiths or beliefs, who almost get to heaven and then are sent back in a loving way....and they have more faith when they come back than they did when they died
