In my case it wouldn't take you five minutes to disprove my claim. It probably wouldn't take too much more to dispose of yours. But when it comes to Jesus of Nazareth, it's not so simple. He had the credentials to back up His claim. First, His moral character coincided with His claims.
Many asylum inmates claim to be celebrities or deities.
But their claims are belied by their characters. Not so with Christ. Jesus Christ was sinless. He was met by silence, even though He addressed those who would have liked to point out a flaw in His character. We read of the temptations of Jesus, but we never hear of a confession of sin on His part.
