Luke 16:19-31, see Abraham and Lazarus.
"If there are NO DEAD PEOPLE, then what is the second death?"
Luke 16:19-31, see the rich man.
" THEN, show me the testimony from God that I am supposed to pray to/through them, instead of directly to God."
I crossed out "to/through", because you've already been told more than 3 times at length, that it is wrong, to use those words, because it is not what they do and you were told why. They are simply asking other folks to pray for them. DO you got it now. They are simply asking other folks to pray for them.
Show me where God forbids that. Show me where He tells you not to ever talk to anyone else. Can you do that? Can you show me where He forbids you to ask someone to pray for you?
