i share this comment by miller regarding why all people do not have nde’s when they return to physical, conscious life:
“remember, it’s not their final death, just a brush with death. if there is indeed a god, he knows the nde is a parenthesis in earthly life [an already but not yet experience i have discussed in my writings], not a final entrance into the afterlife. perhaps he allows only those who need a glimpse of the other side (e.g., for personal assurance or a challenge to life change) to get a glimpse of eternity.”
