Does physical bodily welfare have anything to do with the kingdom of Jesus?

John 18:36 says, > "My kingdom is not of this world. If My kingdom were of this world, then My servants would be fighting, that I might not be delivered up to the Jews; but as it is, My kingdom is not of this realm." If the kingdom of Jesus is not of this world, and he did not request his disciples to fight for his sake, does bodily welfare have anything to do with the Kingdom of God?
