By having an incarnational Lord we can have an incarnational mission, meaning our call to others is real in action and behavior. It is not merely mystical and theoretical, but is based in living in justice and righteousness with the six people groups of the Gospel of Matthew (hungry, thirsty, strangers, naked, sick, prison) these are all physical as well as spiritual issues for living socially just and it is the responsibility of every one who is a disciple of Jesus to engage in this mission.
Jesus came preaching primarily two things: his Father and his Kingdom. The understanding of the Father is to bring us into sonship (or relationship as His children) and understanding of our position with God; and the Kingdom is the rule and reign of God over all who submit as subjects. The only just society will be that which chooses to live as sons (God’s children) with a theocratic based philosophy. All other systems are politically, economically or militarily formed and can only bring limited social justice, if any. The Kingdom of God supersedes and includes all other systems. Nothing will remain socially just for very long without the order and government of the Kingdom of God, administered by the children of God.

Then the king will say to those at his right hand, “Come, you that are blessed by my Father, inherit the kingdom prepared for you from the foundation of the world; for I was hungry and you gave me food, I was thirsty and you gave me something to drink, I was a stranger and you welcomed me, I was naked and you gave me clothing, I was sick and you took care of me, I was in prison and you visited me.” Jesus
