Jesus answered, “My Kingdom is not of this world. If my Kingdom were of this world, then my servants would fight, that I wouldn’t be delivered to the Jews. But now my Kingdom is not from here.”
John 18:36
Being asked by the Pharisees when God’s Kingdom would come, he answered them, “God’s Kingdom doesn’t come with observation; neither will they say, ‘Look, here!’ or, ‘Look, there!’ for behold, God’s Kingdom is within you.”
Luke 17:20-21
The "kingdom" within you, would be the kingdom of the power and spirit, whereas the disciples of Yeshua healed the sick and raised the dead. That kingdom apparently is not within you. Thy "kingdom to come" would be the settlement of the combined houses of Judah and Ephraim/Israel within the lands given to Jacob, with David as their king (Ezekiel 37:22-25).
Ezekiel 37:22-25
22and I will make them one nation in the land, on the mountains of Israel; and one king will be king for all of them; and they will no longer be two nations and no longer be divided into two kingdoms.
23“They will no longer defile themselves with their idols, or with their detestable things, or with any of their transgressions; but I will deliver them from all their dwelling places in which they have sinned, and will cleanse them. And they will be My people, and I will be their God.
The Davidic Kingdom
24“My servant David will be king over them, and they will all have one shepherd; and they will walk in My ordinances and keep My statutes and observe them.
25“They will live on the land that I gave to Jacob My servant, in which your fathers lived; and they will live on it, they, and their sons and their sons’ sons, forever; and David My servant will be their prince forever.
