LOL!
They ALREADY know God is within them.
So, who are they waving at? I just had another "Proddy" (as he calls himself) tell me they are reaching out to get "as close as possible" to God. Sometimes I think the Protestants really have no clue what they are talking about, or maybe they talk form both sides of the mouth.
You are coming from the RCC beliefs
Too much mind reading. I have never been a Roman Catholic.
You will never understand how/why Christians worship as they do since they KNOW God through fellowship.
Fellowship? They are fellows with their maker? The pot is a "buddy" (fellow) with the potter; the chair with the carpenter; the uncreated with the created? More doubletlak...but it sounds good.
Biblical Acts of worship out of sincere hearts are well pleasing to God.
Raising hands thusly is a Biblical act.
Those who have never authentically, sincerely engaged in such sufficiently, have little to no clue about the connection that can be strengthened or initiated by such arm reaching and waving.
God's 'locality' is not nor never has been part of the issue. What a silly, juvenile notion, otherwise.
