In your opinion what causes christians to believe in Jesus

[Sheldon]

Or one could simply read the bible, and see unequivocally that the deity depicted is a capricious, petty vindictive, genocidally cruel mass murdering megalomaniac, largely indifferent to the suffering of its pets.

Bro didn't even allow us to run the study before giving us a demonstration lol. And he didn't even take up the bet. That's called sabotage.

I can only suggest you actually read the bible, and I have taken your bet....bro...

Lets start with capricious, the biblical deity is depicted as torturing a newborn baby to death, out of sheer caprice, as it was conceived in an adulterous relationship.

Petty and vindictive, it is depicted as cursing all people, and for all time, because two of them, it allegedly gave free will, used it in a way it didn't like. 

Genocidally cruel, it allegedly killed every living thing on the planet, as again humans used the free will it allegedly gave them, in ways it didn't like. 

Mass murdering is covered, but one could see the many times the bible depicts it encouraging it's pets to commit wars of ethnic cleansing, infanticide, sex trafficking prisoners, killing off every man woman and child, even their livestock etc etc. 

Indifferent to suffering, well these examples abound, but Exodus 21, where it very specifically endorses slavery will more than do. 

Time for you to hand over the cash...bro
