Maybe you need to define, what Predestinated means ?
There's no play on context.
It is not a bad thing. Not everything is verbatum in the bible. Believe me, if thats true, we would be dead.
God chose you to be saved
God did not choose buddhist john to be saved
He chose "his people" not people individually
As such, if you are not part of his people, you are not saved.
God choses whoever he wants to save by already setting up what group and whoever wants to join, is saved, who doesnt is not. Its common sense, I'll say that instead.
Like the amount of people in an elevator. Only X amount of people are allowed. Most people want to take the stairs. More exercise. Those who use the elevator, are chosen. Those who do not, are not.
It is a play on words (aka its meaning based on context not content). If you choose, you saved. If not, your not. Got chose the saved. Its up to you to be his "chosen" or not.
Without predestination (pre-defining ones destination/place), anyone could be saved. He has to draw a limit by saying "his chosen people." If youre not in that limit, youre not saved.
Those who dont believe they are predestined to be saved, may think that they will be saved just by being here. They are god's children but arent predestined until one physically choses christ.
