Chris Rosebrough has recently done a radio interview concerning the errors of Singapore home-grown heretic Joseph Prince, which can be accessed here. Prince's antinomian denial of the third use of the Law can also be read in Lisa Cooper's critique of Prince's book Destined to Reign, here.
Rosebrough's critique is good. However, I think there is an even worse aspect to Prince that Rosebrough overlooked- Prince's anthropology and harmatology. The problem with Man according to Prince is not such much that Man is sinful (although Prince does not deny that), but that Man stands under condemnation. Condemnation itself is what's bad, and therefore Christ came to erase this condemnation. In the Bible however, condemnation is not bad in itself. Condemnation is in fact the good and just verdict of God on wicked sinners. It is bad for us, because that forensic verdict results in damnation in hell. But if God decided not to save anyone, so that all would be condemned, there would be nothing unjust and God would still remain good. The problem with Man is sin, the solution is forgiveness of sin. In Christ's imputation of his righteousness to believers, the verdict has been changed from condemnation to justification. Both however are just, the former of God's justice, the latter of Christ's merits.
Prince's errant doctrine of man and of sin lies at the root of his heresy. It is because he misdiagnosed the problem that his solution is not the Gospel, however similar it is to the real one. He identifies the problem as one of psychological negativity, and thus the solution is positive thinking. Sin, righteousness- these do exist but merely as the backdrop to the overarching narrative of salvation from the [negative] feelings of condemnation.
