If I may, let God give grace to answer...
Predestination is a very delicate doctrine if you do not know God personally it could lead astray, God knows everything that's an aspect of who he is and he do not hide it from us; let's put it in this way, if you will: we have this gift of choosing whatever we want, no matter good or bad, but God has set a reaction for every action and that cannot be changed, the decision is our but the consequences are God's, that cannot be changed.
Yes, God make a plan to save the world and the way to it but it is written even He changes His mind so if we are fearful of Him and obedient to His word and if we trust in Him alone, he promised to give us what we ask for. In the end none of this matter because he is the beginning and the end, eventually every knee will bow and every tongue will confess that Jesus is Lord.
I, by no means, consider this to be a topic to evade but there are more important things to do and learn about, so that's my answer.
Grace&Peace
