Why do those that claim Christ said something He did not, stop reading the instruction given to read with comprehension the instruction?
Only those ‘children’ who take this flesh journey will have opportunity to ‘see’ the kingdom of God. Those fallen angels nor the devil will take this flesh journey and none of them will exist long enough to see the kingdom of God.
The word ‘again’ in the sense of a ‘rebirth’ spirit or otherwise as was Nicodemus understanding is not what Christ was teaching.
I find it most curious given the first utterance made by Nicodemus to Christ in secret had nothing to do with the subject instruction given by Christ. There is a lesson here but it is not the doctrine of Nicodemus.
If someone doesn't exist in flesh, they don't exist. Your comment makes no sense.
That which is born of the flesh is flesh. We don't take a flesh journey because the flesh profits nothing. It's about becoming alive again spiritually.
When Adam sinned, he died spiritually. Now we need to be born again to see the kingdom. It's not going to happen in the flesh. Flesh and blood cannot inherit the kingdom of God.
