Thou shalt not suffer a witch to live. Exodus 22:18
Some things in the Bible are hard to understand. But this isn't one of them.
The meaning of Exodus 22:18 is clear and simple: kill witches. Kill them whenever and wherever you find them. It is your sacred duty, a direct command from God.
But Christians don't kill witches anymore, do they? Is that because they no longer believe in witches or in the Bible, or both?
John Wesley said that "the giving up of witchcraft is, in effect, the giving up of the Bible."
And he was right about that.
It's time for us all to give up on the Bible. Killing witches was never a good idea, and a good God would never inspire the words of Exodus 22:18.
