TMK, they are vastly different. Very true.
But, I do take exception with our collective Christian judgment of "better". Better implies goodness in the first place. We are not good. What we have is a measure of peace and order. But, even socialist England has that, and so does communist Russia. If we judge "better" by the system's toleration of Christianity, we are on a sliding scale. America would be in the top of that scale.
But, what if "better" is an environment where gospel truth, though rejected and not tolerated by the social order, is starkly contrasted with that order. If that is our scale, America is not better. In fact, I would offer that it makes us one of the most spiritually dark places on Earth right now.
We have another option. We can unplug our minds, our hearts, the grid through which our very thoughts flow, from this entire way of viewing the world and opt for the sole authority of the kingdom of God in Christ. We can and do subject ourselves to the belligerents who dominate this order, and we do so in love for them that they might hear and believe the gospel and be saved. But, our subjection stops right there, on a dime. We do not give one slice of our hearts or affections or allegiance to this order. In this view, and I think it the biblically proper one, none of the world's options are "better", but are realities which we bear and bear witness to them that their end is soon coming.
