Dr. MacArthur explained that the unforgivable sin is unbelief. We are all born in unbelief, if we remain in it, we will experience eternal death, hell. As he expounds John chapter 3, he also explains conversion, the work of God within converts…. If you do not understand John 3, about conversion being a work of God; if you think that you can sign a card and become born again, then please study this sermon, because those modern conversion techniques are UNbiblical
