Did Jesus ever sin?

[Astreja]

Jesus told peter to stop being a foolish man and to put away his sword after cutting the ear off the servant. He healed the man's ear immediately. So don't tell me God has never healed an amputee.

And how do we know this alleged healing really took place?  It's easy to write a story where miraculous things happen.  That doesn't make them factual.  I presume that you believe the story is an authentic historical account, but I see it as fiction.
