1Cr 2:14 But the natural man receiveth not the things of the Spirit of God: for they are foolishness unto him: neither can he know [them], because they are spiritually discerned.
Oh, yes, Pablo otra vez. If you chose to read the Bible in its entirety, instead of using that Reformed Random Verse Generator, you'd find such verses as "ask and you shall find" or discover that even the doubting Thomas was an apostle.
Besides, why should I believe Paul? Who is Paul? Is he God? You believe a man who says God speaks through. Amazing! But it was his foxy salesmanship that did the trick. He was a man who says "I was all things to all men" (it's in the same 1 Corinthians you spout) as long as they bought his story.
He became everything to everyone (by his own words) and said anything anyone wanted to hear just so they would buy into his sales pitch.
