Did the authors of the New Testament believe they were inspired by God?
I would say that the authors were probably just people with a strong belief in a person they thought was beautiful, perfect, amazing, and exemplary. The divinely-inspired part was probably added by King James or the legitimized by the catholic faith or something. But I imagine as individuals, it took a lot for them to not only stick their necks out there(with the climate of the Roman "republic" towards christianity till the days of constantine). Writing and sending information that- given the right Emperor (Diocletian perhaps?) could have gotten them killed. That's powerful. Even if the whole christian faith and belief system is bullocks, that's a powerful amount of faith in a cause.
