Well, you and I are finito. God, for whatever reason, has turned you over to some depraved, wicked, theology, and you will not listen to reason. You will be place on ignore, as I don't want to interact with theology like yours.
So I give Scripture over and over again showing Jesus said no man has entered into heaven at the time Jesus spoke this to Nicodemus (John 3) and Scripture that shows the Living Water/Spirit/Comforter was not yet given because Jesus Christ was not yet glorified (John 7) and no one has dealt with these plain truths with the exception of Protestant connecting Jesus' no man has entered into heaven comment as a "Heavenly teaching" unknown to man, which it was, but at the same time believes Nicodemus should have known this from the OT scriptures, which of course we can't have it both ways. And I get scolded for not listening to reason. I can certainly listen to reason, but you have to reason from the scriptures. All I asked was that you show me from the OT scriptures why Nicodemus should have known about the rebirth?
Let me help everyone out, I know SG has closed his mind, but hopefully others will care to engage and allow the scripture to form our beliefs. Nicodemus, a master of Israel, should he have known about the rebirth? Partially maybe, not much, until Jesus Christ introduced the term born-again and explained it, no master of Israel at the time would have known what Jesus was talking about. Jesus was not really scolding Nicodemus for not knowing, but was expounding on a partially revealed truth found in the OT and showing Nicodemus that He indeed was from God and had more knowledge to give than what had been revealed so far.
Here is the extent of what Nicodemus should have known.....
"Behold, the days come, saith the LORD, that I will make a new covenant with the house of Israel, and with the house of Judah:
Not according to the covenant that I made with their fathers in the day that I took them by the hand to bring them out of the land of Egypt; which my covenant they brake, although I was an husband unto them, saith the LORD:
But this shall be the covenant that I will make with the house of Israel; After those days, saith the LORD, I will put my law in their inward parts, and write it in their hearts; and will be their God, and they shall be my people." (Jeremiah 31)
This was to be NEW, this was TO COME! Jesus revealed this as the new birth.
Now, do you want to argue that having God's law placed in your inward parts and written on your heart is NOT NEW, has always been from the beginning? Go ahead........I'm listening, I won't block you out....
There is no way Nicodemus or anyone else could have understood born-again from all the more that had been given in the OT scripture. After Jesus filled in the blanks, then we know.
The Kingdom of God, which would be Christ in you, a spiritual Kingdom, was a mystery revealed by Messiah.
"And he said, Unto you it is given to know the mysteries of the kingdom of God: but to others in parables; that seeing they might not see, and hearing they might not understand." (Luke 8:10)
