Your too focused on verses about experiences that happened exclusively to individuals. This is inductive reasoning . Where you take one incident and extrapolate from that to mean this happens to all people at all times in the same way . Aka poor bible reading .
My argument is that God knows who will be saved before they are saved, and also that He knows from all eternity what He will call us to.
If He didn’t, He would be imperfect in knowledge, and if He is imperfect in knowledge, that means He is learning as time progresses. If that’s what you think God is like, go ahead. I don’t accept such nonsense.
If God knows what He’s going to do with us before He calls us to a ministry, it’s self evident that He’s already made a choice. As soon as He knows what He’s going to do with us, the choice is made
So my questions to you are...
When did God find out that we will be saved?
When did God decide what He was going to do with us?
When did God choose the purpose He has for us?
Did God do all this before He knew we would believe?
If so, why do you say that He didn’t foreknow or predestine us until AFTER we believed?
Massive holes in your argument.
So your paradigm has God not knowing anything about His plan and purpose for us until we are saved. It’s basically open theism when you carry It to it’s logical conclusion.
