> The government or my employer cannot stop me from mentioning God or from prayer.
Your employer most likely *can* stop you from evangelizing on company property. "Stop you" as in "fire you."
> Just because it is a law does not make it right and if it is a bad law or an unlawful order, it is your duty to disobey.
Ah. So we *should* go back to our Viking roots and pillage churches!
It was illegal for blacks to be at those lunch counters. Or ride in the front of those buses. Or drink from a particular fountain. Or even to swim in the ocean on a specific beach spot. Yet, all those laws were wrong. And any rule, law, or order to prevent anyone from mentioning God is equally unjust.
Go with God and may He bless you all the days of your life.
You are right that private employers can fire employees for what they say, but not so easily can public employers do this.
