“Did I forfeit my salvation?”

What is the punishment mentioned in 2 Corinthians 10? How does it relate to “taking every thought captive”? What is the “courts of Heaven” teaching? Which verses say the Trinity never had a beginning? I’m trying to figure out if I was truly saved long ago. Also, I made a deal with God to give up my salvation in exchange for physical relief from pain. I wonder if I ruined my eternity!
