Jesus walked around the nation of Israel as king of Jews and King of the universe. The Kingdom of God is where ever the will of the King is done. Jesus demonstrated the Kingdom of God to us by healing the sick and setting free the oppressed of the devil. He brought the truth to all who would hear. In the Kingdom of God, the love, provision, power, authority of God flows. Jesus even gave other men His authority over the devil and sickness and as they went in obedience to Him, the same power and authority flowed.
Even so, our authority comes from alignment with the will of the King in His kingdom. We will have all authority over the kingdom of darkness while we are under His authority. The devil only has access to our life in any place we are out of alignment. Proper alignment is when we are submitted to the ones that God has placed above us.

Jesus submitted to God’s plan and stayed in alignment. When a husband submits to Jesus plans and will, he stays in alignment and when a wife submits to the husband’s plans and will she stays in alignment. Likewise, the children and they are all protected.
Friend, the enemy seeks to lure us into rebellion and out from under our covering but we know there is a great blessing in being under authority and willingly submitted to them.
