One can't choose unless they could do otherwise.
To quote someone else:
"Alternatives are entirely unnecessary for the faculty of choice. All that is required is volition. If you willingly do something, you have chosen to do it, regardless of whether or not you would have done otherwise given other options. It's difficult for us to understand because we think of choice as choosing among alternatives. This is mostly because humans are largely without the power to force another to choose something. Sometimes this can be had under coercion, but even then we tend to say we were "forced into it" rather than "we chose it."
Clark gets it very well when he calls it a "mental act" that "initiates and determines a further action." I would further expand it to include "inaction" as well. That makes the definition more complete. Here is an example.
If you choose to jump, but do not, have you chosen to do so? Or have you chosen to _not_ jump?"
Also, Gordon Clark defines choice as:
"Choice then may be defined, at least sufficiently for the present purpose, as a mental act that consciously initiates and determines a further action. The ability to have chosen otherwise is an irrelevant matter."
If this person was ordained to kill he didn't choose to do so. A robot can't choose and neither could one that is ordained to kill.
The person doing the shooting willing engages in the action. It is the intent of their heart to murder. Again, as I have said before, they are responsible for their action because they must give an account to God for what they did, regardless of whether or not God ordained the action (which He did).
You don't blame your computer screen for the writing, you blame the person that is writing the words. The same way you can't blame the person that was basically programmed to kill.
Peter puts the blame on the Jews for the murder of Christ even though Christ's murder was ordained before the foundation of the world (Acts 2).
You guys say God causes evil then that would make God evil.
God caused the murder of Christ (Acts 2) and God works all things after the counsel of His own will (Ephesians 1:11), yet the Scriptures still declare God to be good.
God does not cause evil. He punishes people but that is not the same as causing evil.
Of course punishing evil and causing evil are two different things. No one is saying otherwise.
Sending one to prison is not evil. God cant change mans will irresistibly, if he did he would make everyone believe and accept because he is all loving.
The Scriptures are clear (Romans 9), God could save all, but He has chosen to make objects of wrath fit for destruction.
God does not change man's will irresistibly, no Calvinist (should) claims so.
God created free choice in doing so evil came to be.
What happens in Heaven when I am sure you believe this free will remains? Wil there be the possibility to sin in Heaven?
