Is this possible?
Permitted by God the unknowable Creator?
Has He not at times hidden information from Forefathers, Prophets, Angels, His Chosen Jewish People, hearers of The Parables, readers of Daniel, even The Son?
Large and focused study has been given to modern Near Death Experiences (NDE).
They cannot wholly be dismissed because of any insincerity or mental health of the participants.
The verifiable components of their accounts are quite stark.
The only issues for Believers to discern would most likely be:
1.) Are the accounts coherent with The Word of God in Scripture?
2.) Do they bring Glory and Praise to God?
3.) Are they a substantive part of The Gospel?
4.) Do they present the Jesus we Worship and Serve?
5.) Do to they speak of and show transformed lives?
All these questions have a "yes" answer.
The conversations with Jesus and the perceptions of Heaven are of such incredible Glory and spiritual dynsmic that they have to be authentic.
No denizen of darkness, no busy fictionist, no AI on the loose, no hobbiest, no Pentecostal tongue speaker, no Internet blogger, no money chasing business person could possibly assemble such supreme and Godly accounts.
As such, should we as Believers not more greatly love and adore Christ for these testimonies?
Here we have advocacy of scriptural add-ons.
If scripture does not specifically preclude something, then claiming it is so is ok!!
Nonsense.
I could claim God put invisible pink elephants in orbit around Mars.
Scripture would allow it.
No where does the bible say God did not put IPEOAM!!
We should stick with discerning what scripture says, and then following those instructions.
