I read your post.

I have nothing to do with theology.

As for your baptism example, how does "sprinkling" represent Romans 6? "Or don’t you know that all of us who were baptized into Christ Jesus were baptized into his death? We were therefore buried with him through baptism into death in order that, just as Christ was raised from the dead through the glory of the Father, we too may live a new life." The Ethiopian Eunuch was wanting just a closer walk with Jesus after Philip explained the Scriptures and when water became available, he chose to go down in the water to be baptized Also when John the Baptist baptized in the Jordan I don't picture it like children splashing around...

Word Origin: Derived from the Greek verb βαπτίζω (baptizō), meaning "to dip, immerse, or submerge." - https://biblehub.com/greek/908.htm

If there is no body of water available, I think God understands and won't shut His door in people's faces. However, if one is to be baptized, there is a proper way and a lame way - a way to Honor Jesus and a way uninspiring.

I want to go "all in" with Jesus.

I don't understand why you are judging Scriptures' importance when you claim to have the Spirit of God inside you...
