If Calvin's right, God may have made your friend for the fire, so maybe God is done with him...
Fortunately, Calvin was wrong on his double predestination dogma, among other things.
Then why does He say: "No one can come to Me unless the Father who sent Me draws him (John 6:44); and repeats Himself in John 6:65 "And He was saying, For this reason I have said to you, that no one can come to Me unless it has been granted him from the Father."
If God the Son, repeats Himself, then maybe the argument is not with Calvin, but maybe with the Lord Jesus Christ Himself??
