You can’t or won’t even explain works for the dead. Now you have a hard time understanding the concept of 100%.
Either God is in control, or man is.
I’ll give you a hint......God is.
So you believe in predestination and man does not truly have any free agency? This is the only way God is 100% in control.
If God is truly 100% in control then the only way I can sin is if He wants me to sin, else He is not 100% in control.
