Ed. I won’t use John 3:5, since we disagree far too much on that passage. I still think the fact that Ezekiel ties in with it makes the infusion concept quite clear, but so be it.
However, Acts 2:38: "Peter replied, “Repent and be baptized, every one of you, in the name of Jesus Christ for the forgiveness of your sins. And you will receive the gift of the Holy Spirit.”
This is pretty self-explanatory Ed. Combined with the next two passages (which describe the same event), and it seems very obvious to me that infusion is being described.
Acts 9:17-19:17Then Ananias went to the house and entered it. Placing his hands on Saul, he said, “Brother Saul, the Lord—Jesus, who appeared to you on the road as you were coming here—has sent me so that you may see again and be filled with the Holy Spirit.” 18Immediately, something like scales fell from Saul’s eyes, and he could see again. He got up and was baptized, 19and after taking some food, he regained his strength.
Acts 22:12-16:“A man named Ananias came to see me. He was a devout observer of the law and highly respected by all the Jews living there. 13He stood beside me and said, ‘Brother Saul, receive your sight!’ And at that very moment I was able to see him.
14“Then he said: ‘The God of our fathers has chosen you to know his will and to see the Righteous One and to hear words from his mouth. 15You will be his witness to all men of what you have seen and heard. 16And now what are you waiting for? Get up, be baptized and wash your sins away, calling on his name.’
The above make it clear that Saul’s sins were forgiven at the moment of baptism, not the moment of belief. He did not receive the Holy Spirit until he was baptized, which just so happens to be when his sins were forgiven. This is what infusion means. If your belief is true, Ed, he would have been saved long before, because he had direct revelation from Jesus, and thus his belief would have saved him already.
