"Now the natural man doesn't receive the things of God's Spirit, for they are foolishness to him, and he can't know them, because they are spiritually discerned. "
Paul was full of hooey, just like the rest of the NT.
Me thinks you know more about the Bible then you are aware. At least you know who God used to write Corinthins. Therefore, you must know that ALL MEN will be held accountable at the Judgement Seat for not believing in the Saviour. You will never be able to say, "I never heard of you before."
Please take the time and opportunity "NOW IS THE TIME" for salvation. It is that important. More important than evolution, alignment of the stars, etc.
The Old Testament actually supports this "hooey" since it is a collection of oral traditions with the theme that man has often broken his covenants with God and God has altered the Covenant and re-issued it. The New Testament is is the "new and everlasting covenant" that supersedes all previous contracts between God and man.
