It was maybe three or four decades ago that I came across a book written by a Portestant physician who related NDE’s, and if I recall correctly, they were reports of people he had treated. Additionally, they were NDE’s that were not experiences of heaven, butr rather, experiences of (apparently) hell.
It has been too long since I read it, and I cannot say what happened to the people experiencing them, but my (faint) recollection was that at least some of them had what is sometimes a bit flippantly referred to as a “Come to Jesus” meeting. As he was Protestant, I don’t recall testimony or statement that any of them joined the Catholic Church.
I have been involved with RCIA for over 25 years and do what I can to bring people to the Church.
I also recall Isiah 55:8, and leave some things to the Holy Spirit and to God, remembering that we are bound by the laws God has given us, but God is not bound by those laws.
Will the person in the OP’s post get to heaven? God does not appear to give equally to everyone; and if the individual has responded to the graces God has given them, then I would assume God will judge them accordingly, and it is not for me to know the why or the wherefore as to them.,
