Just answer the main point. Why was the cross necessary if God is able to regenerate man and give him his new birth in Christ before he repents and believes?
Quit trying to avoid the question. After you answer the question then you can challenge my God dwelling in eternity theory.
Try again.
BTW if God inhabits eternity and God acts to regenerate man, then the act of God to regenerate man occurs in eternity. If that doesn't satisfy you then "I can't help you, Sundance."
