Of course you have no intelligent response to what is said at 1 Corinthians 12:3.
And what about the jailer? Where is there any evidence that he obeyed before he believed:
"And brought them out, and said, Sirs, what must I do to be saved? And they said, Believe on the Lord Jesus Christ, and thou shalt be saved, and thy house. And they spake unto him the word of the Lord, and to all that were in his house. And he took them the same hour of the night, and washed their stripes; and was baptized, he and all his, straightway" (Acts 16:30-33).
And if it takes obedience plus faith to be saved then why did Paul only mention believing?
