The case of free will vs. predestination has everything to do with whose eyes you look through. Yes, because God dwell in eternity and sees the end from the beginning, He already knows the outcome of your decision. He looks at the earth's timeline, then chooses those who choose Him. However, to have true children and not robots, God gave us a free will to choose. We can choose to love God, we can choose to hate Him, or we can choose to exchange the concept of God for only what we can see within our puny science. If free will truly did not exist, God would provide a world with only one choice and provide tons of evidence to MAKE you believe. But He does not do that. He provides just enough evidence to allow you to think beyond the physical and into the eternal. But you must decide for yourself. But do not be surprised if God knows your decision the moment you make it.
Yes, God sees our life as a done deal. Yet, we ourselves do have free will to choose. It would be like I could go back in time, meet with George Lucas while attending USC film class. I would know everything about what he would write and the companies he would start. Does he have freewill to write Star Wars? Yes. Would my knowledge change the fact that Darth Vader will be Luke Skywalker's dad? No. It's a done deal because I am not bound by time.
So what is the big deal about free will? Well, those of us with children understand that there is a big difference between programming our computers to wake you up in the morning with "good-morning father-I-love-you" and having your little son or daughter jump on your bed at the crack of dawn yelling "Good morning daddy! I love you!" The Almighty God has a myriad of angels proclaiming "Holy, holy, holy"--but they have seen Him, so it is easy. Think what it means to God, having NOT seen Him, yet lifting your arms and proclaim, "Good morning Lord! I love you!"
Blessed be the God and Father of our Lord Jesus Christ, who hath blessed us with all spiritual blessings in heavenly places in Christ: According as he hath chosen us in him before the foundation of the world, that we should be holy and without blame before him in love: Having predestinated us unto the adoption of children by Jesus Christ to himself, according to the good pleasure of his will, to the praise of the glory of his grace, wherein he hath made us accepted in the beloved. In whom we have redemption through his blood, the forgiveness of sins, according to the riches of his grace. Ephesians 1
