Beware of what?

What does the homeowner want me to believe?

Beware of God, because horrible crimes and atrocities are committed in his name (not to mention a number of atrocities committed by the Big Guy himself, if you are to believe the Bible, Torah, or Koran)

Or…

Beware of God, because if you fail to keep the Sabbath (one of his Ten Commandments), you will burn in Hell for eternity?

I find either option very disconcerting.
