For it pleased the Father that in him should all fullness dwell. Colossians 1:19 KJV
The Word of the Lord tells us that we are in Christ Jesus. In Colossians 1:19 is states that it pleased the Father that in Him (Christ Jesus) should all fullness dwell. So if we are in Christ Jesus the fullness of Him dwells in us.
