A true Christian does not take sides with anything to do with this world or the flesh. We who walk with God and serve God are to remain non-partisan...neutral. We resist the baiting of the devil into a political camp. We love all people...not because of their race or skin colour. We love all men equally. So i can't take any side in this political demonstration of carnality. I must remain on the Lord's side. Carnal men want God for themselves. But He is the God of ALL flesh...yes, even the people you like to hate and blame. All men need to leave their sins behind and go over to the Lord's side. And this begins with they who say they follow Christ.,..but lie.
Being "on the Lord's side" is partisan! It is not neutral or passive. God working in and through us involves our lives in this present world. While I can agree if you are saying that we are not to be "Christian Politicians," "Christian Police Officers" as if such are called that in Scripture; I agree. Yet, God calls us to action; not passivity. When it comes to killing babies through abortion, do we just huddle in neutrality in our "safe-space Churches," or are we to be vocal about an injustice and sin!
Joh the Baptist spoke "against power" in Matthew 14. Peter spoke against the Jewish Leadership and their crime of "nailing (Jesus) to the tree" in Acts 2:23. Jesus was not crucified because He was "neutral" and told everyone what they wanted to hear.
Christians should be involved and desire just and righteous Laws. I agree that the Christian focus is introducing to world to salvation through Jesus Christ and not reformation of secular society. But we are to be "salt and light" to this world. God's Laws are beneficial to society as a whole. God is not a Divine kill-joy, His Laws make for a happier, just society. However, the lack of Christian involvement is that many laws and policies that promote sin, murder and vice are so easily adopted in society. People believe that if something is "legal," it is therefore beneficial and not sinful. Look how the world (America) has changed many Churches to accept Homosexual "marriage" and Homosexuality as "neutral" and "normal."
I have been around long enough to see a transition in the Church. When I became a Christian, almost every Church had a "Brand" or a Denomination displayed on the outside of that particular church building. People started decrying Denominations as evil, divisive, splitting the Body of Christ! That would be unbiblical and wrong! So, as time moved on, Denominational brands started dropping off the names on the Buildings. Many people "separated" from their Denominations and formed their own "Non-Denominational" Churches in the name of not being "divisive"! How was further division of thousands of little independent Churches accomplishing what they said that they were against?
In dealing with many that proudly claimed to be Denominational, and those that strutted themselves as "Non-denominational," I have observed one thing:
The Non-Denominationalist wants to sell themselves and being "Biblical," open to the Holy Spirit, non-confrontational, implying that they are Non-Doctrinal. They have done well selling this image, yet, the most theologically burdened, most rigid and biased people I have dealt with, are the so-called "Non-Denominationalists"! Yes, I run into hard-core theologically committed people from Denominations, but the majority of them are more open and accepting of differences than those I find that come the "Mysterious Holy Ghost of Our Lady of the Mind; Non-Denominational Church."
My point is, many in the Name of Christ have declared non-partisanship and neutrality, and they cannot pull it off. If what you mean is that the Church should not make a political takeover of the Government, or try to make an existing Government a Theocracy; I agree. We are not called to do that.
I disagree if you are saying that we as Christians have no responsibility to elect leaders that do no not oppose Christianity and our values. We are not called to stand by and do nothing to allow unbelievers to place Satan on the Throne.
