“What about “He knew us before we were born”?”
Yes, these NDE stories have the ring of truth and are so common across all cultures and history that it is hard to dismiss them.
But, the idea that we have a pre-existence in heaven before we are born is theologically problematic. That isn’t correct teaching as I understand it.
The reference to Jeremiah about God calling him before birth is usually interpreted to refer to God’s foreknowledge, not our pre-existence.
In other words, God’s knows the future (lives outside of time), not that WE existed in the past before birth.
Also, these scriptures could refer to pre-natal life in the womb.
However, there may be a way to explain encounters with selves who are not yet born as communication from the future into the present.
And so it is “Today we see but dimly as in a mirror”
Remember mirrors were jst polished metal back then...no glass reflections.
One day we too will know.
