Free will isn’t free.
Sin would not exist without free will.
Free will causes sin.
God gave us free will.
No human accepts free will or agrees to it.
No human can avoid free will.
No human is infallible and can choose not to sin.
Sin is a conflict with God.
God’s justice is administered to deal with the sins we have committed.
Justice is the fair resolution of conflict.
A fair resolution to the conflict sin creates is to choose to reject free will.
God has not given us the option to reject free will.
God is not just if he denies us a fair resolution to the conflict sin produces.
Conclusion: Having free will means we are denied justice. God has given us the source of the conflict, and denies us justice when we use it. Free will isn’t free, we pay for it by accepting God’s injustices.
