Libertarianism is the closest in my opinion that matches the spirit of God.
To me there are many realms of thinking that confuse a persons mind about there role on Earth as a Christian
1. The first is the Zionist view that as a christian i should be compelled to establish Israels prominence on earth.Theres many flaws with that.The most basic one is the Golden Rule.Do unto others as you'd have them do unto you.Alot of Christians are so zealous to back Israel they dont care about right or wrong or if others are trampled in the process(mainly the Palestinians)which is in contrast to the Golden rule.
The second flaw in the Zionist way of thinking is that Israel is the most important thing in Gods plan here on earth.While the Jews are Gods chosen people it was only for the purpose to have them be the original seed on earth to establish the word of God.It was not Gods will for Israel to always be Gods system to express his Spirit on earth The Pre-Christ time of Israel was the period where believers(Jews) were under the Law and thus subjected to the style of teaching, where like a parent teaches a child,the people are told to do this ,dont do that because i say so.That system gave the Israel Government authority over the people as a means to teach the spirit of God through laws that they enforced and establish the Temple to make sacrifice for the atonement of sin.
After Christ came we were given the Holy Spirit which took away the need for a centralized platform to express the spirit of God to the world.That started the second stage in Gods plan (which is to raise the people up to be like minded as Him).With the aid of the Holy Spirit we now have the word in our heart and are no longer in need of a teacher to bring us to righteousness.We also have no need for a temple to atone for sin because of Christs resurrection.
This is what brings us to Libertarianism,for now that the Spirit of God is indwelled in us, we have no need for a centralized Government to teach the people righteousness.Through this new system man is given free will through the Spirit to determine for themselves what is right and wrong,thus making themselves responsible for what they do in there life.This idea is why its not Gods will for there to be laws dictating morals, for God will be the only Judge now of the motives of a mans heart.It also goes against preemptive laws.For man alone now has personal responsibility for there actions
.The only responsibility now of Government is to protect life liberty and the pursuit of happiness.
