How does God’s Sovereignty, Predestination, and Free Will relate to one another, in my opinion?

God predestined us using His perfect foreknowledge and sovereignty of what we would do contingent upon whether we would choose to accept or deny Him using our own God-given free will.

If God predestined some people to Heaven and others to Hell before they were even born He would be showing favoritism even though He can technically do whatever He wants within His divine nature (e.g., he cannot lie or deny Himself, and in this case showing favoritism (Romans 2:11) would deny His nature). 

Even though I think https://www.gotquestions.org has tons of valuable information, I disagree with them regarding this statement:

He is not being unfair to those who are not chosen, because they are receiving what they deserve. God’s choosing to be gracious to some is not unfair to the others. No one deserves anything from God; therefore, no one can object if he does not receive anything from God. An illustration would be a man randomly handing out money to five people in a crowd of twenty. Would the fifteen people who did not receive money be upset? Probably so. Do they have a right to be upset? No, they do not. Why? Because the man did not owe anyone money. He simply decided to be gracious to some. (“What Is Predestination?”)

If God is just and fair, this doesn’t make sense at all. It would apply to all of His Creation and it seems people would essentially “luck out” and suffer eternal torment. I’m God, you are not, “turn and you will still burn.” It seems that God would be a psychopathic monster, right?

God elected us in advance knowing we would accept the invitation with our God-given free will. If we didn’t have free will to at least the slightest degree (to at least some extent), God would be the author of evil. We would be robots and God would be the robot master.

Every time we do something evil, we could justifiably blame God if we are orchestrated puppets on a string. 

If Adam and Eve didn’t have free will when they disobeyed God, God would essentially be responsible for bringing evil into the world. 

Therefore, God had the Bible written — to some extent — around what we would do based upon our own free will (Bible prophecy) as He can obviously see perfectly into the future. Similarly, since God knows what we will choose, it couldn’t have happened differently. He knows what we will do before we freely do it.

It’s most likely not this simple and all of these concepts are probably intertwined way beyond human comprehension. I’m thinking God’s Sovereignty, Predestination, and Free Will is like the Father, Son, and Holy Spirit in that we cannot totally comprehend it, but maybe I’m wrong. It’s impossible, much like counting to infinity.

This stuff is definitely interesting, at least to me. Every move you have made and will make relates to what is mentioned, probably for all of eternity.
