I don't understand the concept of predestination. Does it mean that God has already elected those he want to save? Is there any point for me in trying to be saved. Does it mean that no matter what I do or believe, I cannot be saved unless God has already elected me from the foundation of the world? Does it mean I cannot change (in fact even God cannot change his mind since he has already decided on my fate) my eternal state since my fate is already sealed.
