Are you saying that Christ has to be Lord of everybody because He can be my redeemer? That means that the entire world must be converted either by force or by love to Christianity.
I think there’s a tension between the kingdom(s) of this world, and the Kingdom of God.
We do have a responsibility to uphold biblical social ethics—as our rights come from God, not government—and, to quote Allan Keyes, “there is no right to do wrong...” At the same time, the state, and the Church should not be co-mingled. The reason for the rampant secularism in Europe—seeping over and affecting America too—is that most of their countries, due to their age and traditions—have Church and State all tied in together—which ultimately damages both.
I long for a more libertarian system—where government is restrained, and knows its place—but that will also mean more responsibilities for the Church.
Cal Thomas did some calculating a few years ago, and figured out, that if just every EVANGELICAL (not liberal, not Roman Catholic) Church took care of 1 welfare case per 200 of their membership—that this would eliminate any need at all for the government to do welfare....
Of course our government today (and in any day) has powerful forces wanting to expand itself...and will (and always has) forcefully resist any reigning in of its influence or power.
An example given to me by a public school teacher friend of mine is notable: School free-lunch programs have absolutely no control or check up on them. Any family which fills out a form saying they need the lunches gets them. He personally knew of people living in $350K (that’s equal to $500k in California or DC) houses, who drove fine cars....who clearly had no real need—but who’s kids were on the free-lunch program. (All paid for by the US Dept. of Agriculture I believe...)
I believe there’s no motivation by the gov. officials to find and eliminate fraud in this program (as in almost any gov. program) as....its expansion expands their salaries, importance, and power.
