Ephesians 3:10-13

to the intent that now unto the principalities and powers in heavenly places might be known by the church the manifold wisdom of God, according to the eternal purpose which he purposed in Christ Jesus our Lord: in whom we have boldness and access with confidence by the faith of him. Wherefore I desire that ye faint not at my tribulations for you, which is your glory.
