Well actually I am a Born Again Christian with the basic beliefs of a Wesleyan similar to baptist and Pentecostal with a Salvation army bent. I personally think there is only 1 work of grace and sanctification is progressive. And I don’t believe in the gift of tongues like the Pentecostals use it. I believe in the Holy spirit and that gives you any gift he needs you to have.
As for Matthew 3:9 its Hyperbole. God can make a universe out of nothing in our minds. He can literally make nations. His quip about making Sons of Abraham out of stones was a put down as well as a boast and Sarcastic Hyperbole saying their ties to Abraham was pretty thin that those rocks had as much tie to Abraham as they did.
The key is that a child of God is born not by some chemical or some DNA it is about dropping your contempt for God and when you do that he restores you and give you a clean heart fresh new restored and adopts you. So you are a New Creature in Jesus Christ. etc. etc. Not to get into a bible study here but the message of faith Paul talks about is not about lineage but about loyalty and a loss of contempt causing someone to repent and return. The Holy spirit that gives a Born Again Christian “new life” is real but not like honey you mix in your tea.
