Ephesians 3:10-12

[The purpose is] that through the church the complicated, many-sided wisdom of God in all its infinite variety and innumerable aspects might now be made known to the angelic rulers and authorities (principalities and powers) in the heavenly sphere. This is in accordance with the terms of the eternal and timeless purpose which He has realized and carried into effect in [the person of] Christ Jesus our Lord, In Whom, because of our faith in Him, we dare to have the boldness (courage and confidence) of free access (an unreserved approach to God with freedom and without fear).
