Well, perhaps that is true where you live...I cannot say.
But I have lived my professional life out over the last almost 409 years in numerous places.
North Central Texas (DFW)
southern California (Orange county)
Northern California (Livermore)
Ohio (Cincinnati)
Montana (Dillon)
Utah (south of Salt Lake City)
Idaho (Boise area)
In none of those places would I have ever characterized my own strong belief in Christ or America as a gross minority. Not even close.
Now, I understand that there are places, perhaps particularly the inner cities, and in some very liberal bastions of so-called higher education on the East and West coasts), where that may be the case.
But right now in Idaho I can truthfully say that it is the other way around. I can say the same for the entire Intermountain West, the same for my birthplace in North Central Texas, and most places in Texas outside of some areas of Dallas, Houston, and Austin, etc.
No, IMHO, the situation is not nearly as bleak..at least from my perspective...as you might imagine.
There is hope...and we can pray that that hope is realized. I know I do...and I do and will continue to pray for, work for, and fight for it the best of my ability. And, to teach my kids and grandkids to do the same.
Christianity might as well be a minority given the fact that the culture as a whole in this country and the corruption we witness in every single institution that exists is a testament against us.
At best Christianity has become Lukewarm in America. At worst - indifferent and wholly corrupted itself. The fruits of this lethargy are self-evident if we are honest with ourselves. Christianity lost this culture to the hedonists and the Statists. We surrendered it without much of a fight.
This government reflects the abased culture that permeates it.
We have arrived at the time where evil and tyranny is entrenched, and it is not going to allow itself to be restrained. Once a few brave souls stand up to tyranny - they get slaughtered, arrested and tried in the court of public opinion that preaches THEY are the evil ones, while Christians shrug their shoulders, say to themselves that those who resisted had it coming and go back to themselves and their comforts. Ruby Ridge, both Wacos, Kim Davis, people who exposed Planned Parenthood, now this. Those are no longer the rare exceptions, they are becoming the rule in this country.
If people do not understand where we have arrived and recognize the absolute critical danger their children and what remains of their wealth, property and liberty are in, then resisting this Beast that now rules us is going to be an exercise in absolute futility and genocide awaits us and our posterity.
We are past the point of praying and hoping. We are almost past the time of standing and and resisting, because what shortly follows that is the time of fleeing and hiding.
