The Bible says...

The Bible says that we shall kill unmarried virgins, homosexuals, those who work on the day of the sabbath(whatever day that may be), but then it says "Thou shall not kill" and that only those free of sin can "cast the first stone." So, I'm confused, am I to kill sinners by stoning or burning them to death, or not? If I do, will I be exempt from prosecution because I am following the commands of the Lord? Will that work in a modern day courtroom?

Is it just me or does the God of the Bible command us to do some pretty wicked things in his name? Well as they say "the Lord works in mysterious ways."
