This is not a passage that I understand to be refering [sic]to eternal life election/predestination.
You are wrong. Believe the Bible.
For one reason no one would give God glory for fitting someone for destruction in hell, the idea being God showing wrath to vessels of destruction so the ones having obtained mercy can give God glory, they wouldn't know they ended up in destruction to begin with, therefore how could they give God glory? It has to refer to the living and national (historical) circumstances where God judges the kings and nations of the world in the world, whereby the destruction of one nation (Egypt) provides for mercy and the salvation of another nation (Israel).
Pure philosophy -- not scriptural.
There you go again, your interpretation = infallable [sic]and authoritive [sic]truth.
I'm just being biblical. The Bible is the authority -- not me.
