Reprobation, in
Christian theology, is a corollary to the
Calvinistic or broadly Augustinian doctrine of
unconditional election which teaches that some of mankind (the elect) are
predestined by God for salvation, and the remainder, the reprobate, are left bound to their fallen sin nature to be condemned to
damnation in the Lake of fire. Similarly, when a sinner is so hardened as to feel no remorse or misgiving of conscience, it is considered as a sign of reprobation.
