Don't change the subject.  I said "you", not "God".

If the morality is absolute and true as provided by God in the Bible, you should be killing everyone who works on Saturday or is gay.

If you don't, you are either immoral or get your morality from somewhere else, i.e. your morality is not absolute.

Just admit that morality is not absolute and it does change over time.

When was the last time we burned someone at the stake for criticizing the church?  Why are we not doing it now?
When was the last time we delivered electroshocks to gay people?  Why are we not doing it now?
