So that He can masturbate to all the suffering that He's caused?

Just kidding; God's not a sexual sadist^{[citation needed]}, He's actually an exhibitionist, and gets off on flashing His privates to His prophets. See Exodus 33:23 (in which God famously moons Moses) and Ezekiel 1:27 and 8:2 (in which Ezekiel actually gets a good look at God's genitals, and describes them as being made of fire, though that just raises further questions).
