I would argue that for a prophecy to truly be of divine inspiration, it's accuracy rate would have to be 100%. Anything less would not be Divinely inspired, unless God can be anything less than 100% right, which by definition would make God not God, but less than God.
Good point.
God, of course, IS flawless
our human hearing is not always so--especially given that few are taken to the back side of the desert for 40 years to clear up their pride and other hearing issues.
But I do believe God is going to clean up HIS AUTHENTIC PROPHETIC before things totally wind down. But there will be false sorts until the end.
And, I need Grace so I extend Grace as long as there's any evidence of a genuine relationship with Christ.
