I think there are problems with associating Jesus’ power and high intelligence.
I think the problem arises if we think that high intelligence (by our measurement!) is an essential element of Jesus's mission.
The author contends, for instance, that Jesus's miracles of healing required high intelligence to "repair" cells and so on ... and yet we know from the Bible, as well as other history, that the apostles performed miraculous healings and raised the dead. The prophet Elijah experienced miraculous multiplication of food and manipulation of the weather. They can't all have had the highest IQ ever!
