Someday, I want to meet a Calvinist with enough integrity to admit that he's a reprobate. Because, if _all_ Calvinists are really as elect as they say they are, then their salvation is absolutely by "works" -- the work in question being that of knowing the (allegedly) correct Calvinist doctrine.
After years of study and research, the uberboffins at CERN determined that the sound made by a paradox like that is "KRONG!"
By the grace of God, I think you'll have a long wait.
Perhaps I've incorrectly assumed you know the defintion of "reprobate."
A reprobate is one who has not been named to be among God's family and who has not and who will not and who doesn't even want to receive God's grace through faith in Christ.
All who ask Christ for His salvation will receive it, as He has promised His "living water" to all who thirst.
The reprobate does not ask for Christ for salvation because he thinks he does not thirst. And if he does, he satisfies that thirst by other means.
On God's earth, there are only two types of people -- the reprobate who is condemned by the sin of his disbelief and the redeemed who is acquitted of his sins by Christ on the cross, and is thus saved by God's unmerited mercy through faith in Christ.
What Christian believer would ever call themselves a "reprobate?"
