If we had the proof of His existence then how us, mortals, could oppose His will?
God has left a tiny area of free will open in us. It has to do with aspects of faith that we have in Him. It doesn't have anything to so with any of our standard understanding of free will, like choosing which side of the bed to get out of in the morning.
Our free will has to do with limited aspects of our faith in God. That's it. God judges us according to our faith in Him.
Then how could He test us?
God tests us based on the freewill portion of our faith in Him.
...the area of free will...
That is something I can
prove false...
If you believe these 3 common Christian beliefs:
1) God created the universe exactly as it is
2) God could have created the universe differently if he wanted to (billions of possibilities)
3) God is Omniscient (knows the future)
Then free will
cannot exist
God created
this specific universe, knowing exactly what would happen, including your personal choices (free will)... he could have created a universe where I was a Christian instead of an Atheist, but God created this universe, knowing that I would be an Atheist...
It's God's fault I'm an Atheist, not mine!
A point about free will and prayer...
When you pray for God to change his divine plan to benefit yourself... You claim that you know better than God does? You ask him to change his perfect/divine plan because your kid has cancer?
Who are you to question God's divine/perfect plan?!? God gave your kid cancer because that is
His plan, and
you think you know better than God? The lolz
Well, that isn't quite the way God has it expressed all over the Bible. From

There are many more passages at the site listed. Many of the passages express how God gives us free will.
The idea of cause and effect suggests that there is no free will. But how can one talk to a materialistic scientist who doesn't believe in spirit and soul, but only believes in bio-mechanical operations of mind?
It seems that you can barely stay on point. Are you a mind reader that you know my underlying assumptions enough so that you can examine them? If you happen to know my underlying assumptions, are you so foolish that you think that you can judge their validity fairly?
