I do not quite know what to make of the teaching of "predestination".
If it is the case that people are foreknown, therefore predestined, therefore called, therefore believe, this, taken in a vacuum, would go hand in hand with other Scriptural doctrines (you didn't choose Me, I chose you; I will lose none; no one can snatch them out of My hand ; if they were of us, they would've remained with us); but, since this seemingly conflicts with the teaching that believers, whom God has "grafted in" due to their faith (so they really have saving faith--they didn't "trick" God), can also become unbelievers and be cut off (Ro 11:17+), could it not be the case that the "predestined" language and doctrines apply to those who are believers, yet it somehow no longer applies to those who fall away?
This would agree with my position that the fact that God "forgets righteousness" (Ez), as mentioned in other threads, manifests itself in God blotting names out of the Lamb's Book of Life, and, thus, their righteousness being "forgotten", it is as if they were never saved... leading to the paradox of "if they were of us they would've remained with us" being preserved by the fact that they are accounted as having never been saved in the first place (if they are "blotted out", "forgotten").
However, this would seem to undermine the certitude , the confidence (eg, expressed by Monergist types here), the entire effect, that, aside from it actually being true, believing in the teaching of predestination seems to be aimed at producing.
