Then how did we always have one without the other until recent times?
We haven't. We have always had both. It has always been the law that you are allowed to practice whatever religion you want, or no religion at all. And it has always been the law that there is a separation between church and state, a prohibition on government to be religious.
If you deny God, you embrace Satan, and until fairly recently that would have meant you'd be locked away in a mental asylum.
Our country has a history of poorly following the constitution, but the law is the law, and the law says we have the freedom to believe or disbelieve.
You're so fixated on this.
As are you it seems.
If you insist, yes, a light-bulb "serves" its master
A light bulb has no agency to server anything.
We have two possible states, in which we cling to God or Satan.
It's not just the states I take issue with though. And the states you list are a false dichotomy as evidence by the sports analogy from earlier.
The evidence is within you every time you choose to reject God. Indeed every time you type a character in reply to me, you evidence free will.
Just saying something is evidence doesn't make it evidence.
"The complete lack of life in the universe outside of our planet is evidence that god doesn't exist!"
One can say that and be entirely wrong.
The entire premise requires us to arrogantly suppose we could possibly control the whole planet, which is contrary to everything God tells us.
God gave us dominion, what is dominion if not complete control? And again, we definitely have the power to do so because there is mountains of scientific evidence showing that humans are responsible for climate change.
And they are entirely applicable to the climate agenda. When we are humble, we put our trust in God, not ourselves.
That's all assuming you know god's plan which is heretical. Unless you know his plans (you don't) then you should assume the worst case, that god intends for us to deal with the problem on our own.
Responsibility for our own actions should be the default. I don't mean to be glib but of all people I would have hoped a conservative would understand that.
