I consider that the massive number of people today who claim that slavery is wrong, to be better than Jesus.
I expect a Messiah, on being born into a particular world, to see human rights abuses and then reacting PERFECTLY to that stimuli.
A perfect reaction would be to come up with a set of rules similar to the rules that the Australian (etc) government have today - laws that outlaw slavery, rape, etc etc. I consider Australian law to be head and shoulders above the bible, which condones slavery (Leviticus 25:44, Ephesians 6:5, Colossians 3:22).
And then go ABOVE Australian law and free people from state-slavery as well (ie people suffering under dictatorships).
And also address what was causing individuals (not governments) from doing evil, even while claiming to be Christians and believing in God.
So fix the problems with both governments and individuals.
Jesus woefully failed to do any of this, and it is so easy to be better than Jesus simply by saying "slavery is wrong, unlike what the bible said".
