Best way to understand Predestination is through the analogy of a video game. The game's creator decides which characters in the game will be good and which will be evil, that's it. The characters have no say in the character that is assigned to them, that choice rests solely with the creator of the game. This is exactly what the Bible teaches; God has decided beforehand who will play which character, Free Will is a Hollywood myth! If you don't like this God, go find another one that is better, and that my friends is the definition of a fool's errand - you are not better nor will you find any angel, human or devil that is better. Understand God for who He is, quit trying to fit Him into a mould you think He should fit into! Go and create one blade of grass, one drop of dew, one breath of wind, and then I might consider the possibility that you may know better, till then quit your fool's errand and just read your Bible, don't read into it, and definitely definitely do not add to it or subtract from it!?
