Let me tweak your claim ;

I would argue that the Bible does not clearly express the notion that Jesus is... good.

Even most atheists would answer :
No you are wrong , he was a good person
And they would be right

However some part of the new testament have alwayes baffled me :

Jesus is passing by a fig tree
He wants to eat a fig but it is not the right season for figs
" Be damned for ever, let nobody eat your fruits anymore " Jesus said and the poor tree dries up

What's the meaning of such a sad parable ?

Of course I have no doubt that teologians knows the answer
