"You have your word and experiences against someone else's words and experiences."
I have no word or experience, I am not making the claim. He who claims proves.
"The test of whether or not something is true is if the source of the information comes from an authority on the subject."
We are not debating if the scriptures are true but the claims of the claimant. Satan used scripture to tempt Jesus, were the scriptures true...yes. Does that make Satan's points correct? Of course not.
This is the verse in context:
18 But as surely as God is faithful, our message to you is not “Yes” and “No.” 19 For the Son of God, Jesus Christ, who was preached among you by us—by me and Silas[
c] and Timothy—was not “Yes” and “No,” but in him it has always been “Yes.” 20 For no matter how many promises God has made, they are “Yes” in Christ. And so through him the “Amen” is spoken by us to the glory of God. 21 Now it is God who makes both us and you stand firm in Christ. He anointed us,
22 set his seal of ownership on us, and put his Spirit in our hearts as a deposit, guaranteeing what is to come.
23 I call God as my witness—and I stake my life on it—that it was in order to spare you that I did not return to Corinth. 24 Not that we lord it over your faith, but we work with you for your joy, because it is by faith you stand firm.
These verses do not validate a claim of personal Holy Spirit Baptism. You are reading yourself into the pronouns.
