All rights in the US Constitution come from God? So it was amended 27 times for what reason? He couldn't get it right the first time? Oh, and God decided to repeal the prohibition of alcohol because he just changed his all-knowing mind?
What about other nation's constitutions? The Australian Constitution opens like this:
"Whereas the people of New South Wales, Victoria, South Australia, Queensland, and Tasmania, humbly relying on the blessing of Almighty God, have agreed to unite in one indissoluble Federal Commonwealth under the Crown of the United Kingdom of Great Britain and Ireland, and under the Constitution hereby established."
So why does God think some countries should be under the Crown of the United Kingdom, and some should not? Why does God think that in Australia, the "laws of the Commonwealth shall be in force on all British ships, the Queen’s ships of war excepted", for example?
The Crown has divine approval in countries like Britain, Australia, Canada, New Zealand and other Commonwealth countries. But I'm guessing you wouldn't like the thought of that in the US. Better to just pretend the US has some divinely inspired constitution, and conveniently ignore other countries where the same God is invoked as the source of authority for the monarch.
Constitutions aren't made by God, they're made by people. If God came up with the rights of the US Constitution, why would he see fit to give other nations different constitutions with different rights, under different types of government?
The US Constitution is an amazingly important document that you are fortunate to have. Please do not sully it by attempting to graft magical authority to it. It is a far more valuable achievement without you attempting to jam God in it with your filthy lie.
