Satan still faces the Holy Spirit as the restrainer so satan absolutely isn't there yet. When the Holy Spirit is removed, absolutely everything will be under satan's control, big government, big church, big business.
But Satan is in control of ALL earthly Kingdoms as his words testify in Christs temptation in Lukes Gospel
Jesus spent most of his life working in the small family business. God did not do this by accident. I know that widows and the poor got very special Christ like treatment. Paul earned his way by tent making even though he teaches that those serving the church deserve to be supported. No handout was provided by God who values work.
I think Christs early life as a carpenter just goes to illustrate the humble origins of the Son of God who didnt come from powerful Human Institutions and further re-enforces his words that His Kingdom is not of this World. You seem very down on "handouts", do you ever see them as "Hand ups" for someone desperate and in need who needs material help. I have been in need of "handouts" at times in my life and they were neither soul destroying or made me feel worthless but were indispensable in getting through hard times when money was in short supply.
God called Paul out of big church. God/Jesus never reformed big church.
God called Matthew out of big government (tax collecting) to become his sheep. He never reformed big government (big church erroneously expected the Messiah to reform big government).
The ruling institutions of the time, as now ,are indeed un-reformable as they are controlled by the Devil, Christ came to show us the way of Love and compassion and transform our own lives, and through them wider society, but the powers of Governing, be they State or Church were too far gone to be changed. thats how i read it anyway.
Big church and big government colluded to kill Jesus which he predicted and allowed.
Big church and big government (nowadays also big business) is the broad path.
Jesus is the narrow path (little church?).
God grants power to big government (nowadays indistinguishable from big business). He also predicted and is allowing where that takes the world.
I dont see the distinction between Big and small, unless its the power they wield, we are ALL Evil, all transgress Gods laws and ALL fail to build our lives on the solid rock of Christs truth, the only difference is those that profess to follow Christ, however wretched our lives, at least try to follow his commandments.
When a Christian neighbor shows love and behaves as Jesus has instructed, the recipient of that loving assistance is uplifted and may even lead to a person being saved.
When a satan infiltrated big government behaves as Karl Marx has instructed, the recipient of those big government handouts feels worthless and is destroyed. The difference is love vs no love (Jesus vs anti-Jesus).
If you and your family lived in Gaza, or Sudan, or Ethiopia where famine and war stalk the land, then you tell me that unless you are being given help by a Christian then that help is "worthless and destroying". In fact the opposite is true, for if no Aid was given out then that would lead to the destruction of tens of thousands of lives. Do not denigrate help for those in need, even if given by a non believer, for saving lives and preventing suffering is never worthless or Soul destroying.
I'm not willing to talk about governing. Big church once erroneously expected the Messiah to reform big government and I'm not repeating that mistake.
Well you raised the issue of North Korea/South Korea. China/Taiwan, East/West Germany, but i would just reiterate that as Christians we can be neither left or right, liberal or Conservative, but "Christ Centered" only, for anything more is a betrayal of our lord and Saviour who should reign supreme in our lives and be worthy of ALL our Love and Devotion.
