Are you saying that everyone who disrespects his parents, commits sodomy, worships false gods, or commits adultery should be executed?
God said certain crimes were serious enough to justify killing the criminal.
Do YOU think God was unjust? Unrealistic?
Do you believe the God of the Old Testament was a Mean Old Man, and the Jesus came and changed God into a sweet, anything goes person? Or did Jesus banish the God of the Old Testament to the attic, where He is now hiding until the end of time?
What is YOUR theology?
Did God change between 1000 BC, 33 AD and 2014 AD?
