What the Bible says about
(From Forerunner Commentary)
Everyone of us knows that we are in the church. Are we aware that we are already in the Kingdom of God? We are! It is not here in fullness, nor as a physical reality. This verse says very clearly that we are already in the Kingdom of His dear Son. This is a spiritual reality that we must consider in relation to the church to grasp the importance of the church. The church is a portion of the Kingdom of God. It is not its fullness but a part.
John W. Ritenbaugh
