They are Crazy!?!?

Jesus has risen from the grave.  The disciples see him as well as three women.  Yet, it does not end there.  According to Paul, over 500 saw Jesus at one time.  That is a lot of witnesses to an event. 
 
On top of this, every disciple and witness to Jesus’ return never denied it even at death.  So, it had to be real.  Jesus had to come back from the grave.
 
For everyone to die telling the same event, is insane.  It is truly unreal.  It happened.  No one changed their account.  No one declared it a lie.  They all died saying the same thing.  Jesus is alive.
 
We have heard crazy things in our lifetime.  Most of these are just stories, with no truth behind them.  But with Jesus, there are too many witnesses for this to be a lie. 
 
Therefore, the question is simple: are theses individuals from the past crazy or are they telling the truth?
