My friend John Hendryx writes:

Until the Lord Jesus Christ returns and establishes justice (Rev 6:16, 20), Christians are to advance the kingdom of God through proclaiming his word with love and persuasion. Aside from the secularist hysteria about the dangers of Christian theocracy, the vast majority of Christians actually have no more interest in establishing a theocratic Christian state, than in establishing a purely secularist state. Both are equally loathsome to us. Here is why. The secularist mullahs are just as dangerous as the Christian ones. Too much power in the hands of anyone, including certain denominations of Christians, is dangerous because man is corruptible. That is why limited government and a balance of power is a reasonable idea, because it understands the sinful limitations of human beings, whether they be secularist, Christian, Muslim or Buddhist.

Even though Christians know the only truth, they also know themselves too well as sinners to be without the restraint of law or a balance of power. So when Christians speak of separation of church and state we include all ideas under this umbrella, including secularism. One thing many secularists fail to realize though, is that neither they nor their ideas are religiously neutral. Yet they seem to have convinced themselves that they are neutral…. even though (ironically) the secularists want to vigorously impose their own moral code on society, ideas which have both affirmations and denials about the nature of good and evil. Even in the face of this obvious truth, the secularists amazingly still want to exempt themselves from the separation of church and state clause. It is amazing to me that they do not see how very exclusionary of all other ideas this is and leaves power in the hands of secularists alone. They think, “others are forbidden to speak in the public square because they are religious but WE CAN because we are not religious.” But if, on the other hand, we understand the separation clause more broadly, wherein all views are included under the separation of church and state (that is NO religion can be established, including secularism) then ALL religions and worldviews can speak freely in the public square and compete in the free market of ideas… That is closer to true liberty. Remember, we live in a secular country, not a secularist country.

So because of the sin nature a good Christian should never be anti-government (because all government is established by God) but he should believe in a limited government and rule of law so as to promote the most good by avoiding the tyranny of any one group, including his own. Let’s say Christians did get power. Which Christian denomination will you trust to impose laws on the USA? If you know yourself and the nature of man well, you will answer that none should have such power. The Lord alone has the omniscience to judge right and wrong and do it with absolute justice and equity when He comes. For now we are to win people’s hearts and minds through the gospel, which God uses to change hearts, and which ALONE will make people eager to follow God’s laws. He can gather people for his kingdom under any type of government. Some of the biggest revivals in world history have taken place under the most inhospitable of regimes. So we fear no man or law for what can he do beyond kill our body? Nothing.
