The idea that Christians with biblical Universalism views do not belief in afterlife punishment is a mistaken one. We disagree that it is eternal and view it as something one goes through before ascending to Heaven restored from turning away from God.
I also think that Dr. Brown is mistaken about what Joseph Prince teaches and believes. He does not Condon the idea that Sin is a free for all due to Christ's work. Neither does universal reconciliation/restoration estethology. I think that his views that are on supernatural wealth and prosperity are something more disagreeable.
