If you turn on the news, read a newspaper, even listen to many sermons these days, you will inevitably hear about this "War on Christmas".
The idea is that school shootings, the fall of the economy, bad presidents (whichever ones you dub that way), unemployment, divorce, and faltering church attendance can all be attributed to our nations respect and preservation of "CHRISTmas". That without our labeling December as "The Christmas Season", and without our schools allowing formal corporate prayer time, we can force God out. We can force him to abandon our schools, our marriages, our churches, and our Country.
Now, don't hear me wrong, I would love the whole country to embrace Christmas, but we haven't done that in nearly a hundred years (what? You thought our buying our kids great presents, hanging shiny Christmas lights on our houses, and getting all dressed up for Christmas church service was about Jesus? Seriously?)
I do, I wish EVERYTHING revolved around Christ, if it REALLY revolved around Christ. But having a government that mandates Christianity as the 'official' religion doesn't make us better Christians, in fact, I would argue that it makes us Worse Christians (see ANY example of how the church thrives under martial law and persecution vs. how it dies an apathetic death in the presence of sanctioned religious freedom).
When Jesus walked the Earth, the Roman Empire did not endorse him (his own people didn't even endorse him), And yet, Somehow, he was still the son of God and still able to be raised from the dead on the third day anyway.
The first century Christians did not have national holidays set up on their behalf and yet, remarkably, they still were able to perform miracles, pen letters that survived thousands of years, and grow the Church.
For centuries (and in Many places to this very day) Christianity wasn't protected, at best, and violently outlawed, at worst, and yet God still managed to be... God.
God does not need the empire (not the Roman nor the United States) to formally recognize him in order to be God.
God does not need government to give him the nod of approval in order for him to show up and do his God thing.
God does not need a School to call 'winter break' 'Christmas' break in order to be able to still be God.
If a "war on Christmas" (aka: people saying 'happy holidays') is all it takes to remove God's ability to show up in our homes, our schools, and our nation, then we are wasting our lives and worshiping the wrong God.
