For the kingdom of God is not a matter of eating and drinking, but of righteousness, peace and joy in the Holy Spirit, 

Romans 14:17 (NIV)

The Lord Jesus in His earth walk was the embodiment of the Kingdom of God. Where He was, there was the Kingdom of God, His word, His presence, and His work, there was the demonstration of the Kingdom of God. To locate the Kingdom of God then, you had to locate where He was.  To know what the Kingdom was doing, you had to know what the King was doing!  Today, to locate the Kingdom, where the King is, what the Kingdom is doing, you have to know the Holy Spirit. Locate, know and be in the Holy Ghost.
