>Were he such a fantastic healer, driven by the power of God, why is he not sweeping the nation, curing all the otherwise-incurably sick?

A) He's dead[1] B) Jesus did this, and, as you can imagine, people weren't willing to see this as "attributable solely to his god". Even I can think of other explanations (e.g., fraud) if a person were going around the country loudly proclaiming themselves to be using God's power to heal anyone and everyone.
