Good behaviour has good results. Bad behaviour results in punishment and suffering as natural consequences OF that bad behaviour.

If it's that way in secular life, and it bloody well is, then why the hell shouldn't it be that way in religion too???????????? As above, so below. What's sauce for the goose is sauce for the gander. You commit the crime, you pay the price.

I gather you don't object to secular society controlling people through fear of punishment when they break civil laws. Why would you object to the church attempting to control people through fear of punishment when they break spiritual laws?

Not very New Testament, this lot, is it?
