A challenge to you interpretation of predestined:
Romans 8 :29- For whom he did foreknow, he also did predestinate to be conformed to the image of his Son, that he might be the firstborn among many brethren 30 'Moreover whom he did predestinate, them he also called: and whom he called, them he also justified: and whom he justified, them he also glorified'
Your stance being that whoever he predestined to become saved will be and that if he does not predestine themtthey wont be. Everyone.
But wait a minute what about 'many are called few are chosen' Matt 22 14. Although i appreciate the two greek words are different..
This would seem to put a sifting process in the cascade. so not everyone called is saved? So not everyone predestined is saved. How can this be? Has God failed in his predestination?
Maybe you have misunderstood this Predestined?
From above 'Whom he did' for know (i suggest this is everybody) he also did preddestine (everyone to be saved?) but then comes called, not everybody called is saved. Your definition does not hold
I suggest God just predestined everybody to get to the stage of being called after that it is down to human choice, This fits in with my view of God and goes yours- the discriminatory lover of some men and not others This ties in with God wanting everyone saved. (1 Tim. 2:3–4), (2 Peter 3:9).
