Greatest Claim In History?

As CS Lewis pointed out. Either Jesus was a liar or a fruitcake or He was telling the truth. 
The option nobody has is simply to claim that 'He was a good man'.
If Jesus was mentally ill - look at ALL of His claims - then goodness does not enter into it.
If he were a liar - clearly He was NOT 'a good man'.
Healing the sick, raising the dead, BEATING DEATH HIMSELF all give clues but ..
... the absolute proof comes when you commit wholly to Him and discover the reality of His presence for yourself.
