Jkag,
I think pouring is great!
Acts 2:33
"Therefore having been exalted to the right hand of God, and having received from the Father the promise of the Holy Spirit, He has poured forth this which you both see and hear.
Acts 10:45
All the circumcised believers who came with Peter were amazed, because the gift of the Holy Spirit had been poured out on the Gentiles also.
But I think sprinkling is great too…
1 Peter 1:2
according to the foreknowledge of God the Father, by the sanctifying work of the Spirit, to obey Jesus Christ and be sprinkled with His blood: May grace and peace be yours in the fullest measure.
Isaiah 52:15
Thus He will sprinkle many nations, Kings will shut their mouths on account of Him;For what had not been told them they will see,And what they had not heard they will understand.
Hebrews 10:22 let us draw near with a sincere heart in full assurance of faith, having our hearts sprinkled clean from an evil conscience and our bodies washed with pure water.
Peter 1:2 according to the foreknowledge of God the Father, by the sanctifying work of the Spirit, to obey Jesus Christ and be sprinkled with His blood: May grace and peace be yours in the fullest measure.
Now Baptists say that emersion is the proper way, because the word only means that, but really they dunk, they don’t normally lay people down, and when they do, people are normally holding their nose, and it does not look like they are dead, but are kind of fighting that process in holding their noses, and contorting their faces, to pinch shut their eyes tight. If there is any symbolism in that, it looks more like a willful insistence not to see at the moment…

IN any case, there are no verses in the scriptures that I can see where either laying down in water, being covered by water, or being dunked in water have greater meaning in all of the types and symbols found in the scriptures, or the Holy Spirit coming upon them, or being washed in the blood of the lamb such as pouring and sprinkling do.
