This quotes Timothy Keller in perhaps the most idiotic thinking I have seen in a very long time. If Jesus rose from the dead you HAVE to believe everything he said! The problem here is, we have nothing about what Jesus said, only later authors who imagined he said this or that. There are no eye witnesses to anything about Jesus in the Bible, all of it being written after he was long gone, and none of it by anyone who ever saw or even heard anything he said....... And even if he rose from the dead, giving the benefit of the doubt to it, I don't see how it follows that I have to believe everything he said.
It's a twist on the law of the jungle. Instead of the survival of the fittest, Keller's "point" is that one who possess a supernatural power must also be correct about everything the he pontificates about. That is simply a non sequitur.
