The Lord’s body is disciplined and works in harmony, because all parts are in agreement. There is no division, because all of its elements are important and are part of this Body. There are people waiting in line at the hospital for a liver transplant because their own liver is no longer working.
The Kingdom of God is made up of perfect discipline. The Church, like the Body of the Lord Jesus Christ, He being the Head, is formed by those who are born of the Spirit of God. This body has harmony because it works perfectly.
