Yahweh Rules in the Kingdoms of Men
True Christians, who believe the ancient things concerning the Kingdom of God and the name of Jesus Christ, realize they must not participate in politics or other governments of today's world. The Bible explains we are to be separate. God says "Come out from among them and be separate." Jesus said "my kingdom is not of this age, if it were, then my servants would fight".
Christ died on a tree, we are told that in the New Testament. He was nailed to it, and lifted up from the earth on it. Adam and Eve had grasped for knowledge from the tree of the knowledge of good and evil. Therefore thier way to the tree of life was blocked by God. But Christ, allowed his sinful human flesh (although he did not sin) to be nailed to a tree, and crucified to display the value of flesh - none. He offerred his own blood to God demonstrating that God alone is righteous. And so Christ becomes the tree of life for us, the way to which is once again opened. He explained that faith is like a tiny mustard seed. Luke 13:19 "It is like a grain of mustard seed, which a man took, and cast into his garden; and it grew, and waxed a great tree; and the fowls of the air lodged in the branches of it." His kingdom started out tiny, just him. But, he has been calling to those people who are willing to become spiritually minded, birds who are lifted up by the Spirit - the word of God and can lodge in his tree. Once he returns and changes those people to flesh and spirit after they are judged, they will be completely exalted, and dwell in this giant tree which will be the Kingdom of God on earth. From that they will rule the world.
