Ephesians 3:10-11

His intent was that now, through the church, the manifold wisdom of God should be made known to the rulers and authorities in the heavenly realms, according to his eternal purpose that he accomplished in Christ Jesus our Lord. 

His intent was that now, through the church, the manifold wisdom of God 
Romans 11:33  Oh, the depth of the riches of the wisdom and knowledge of God! How unsearchable his judgments, and his paths beyond tracing out!
1 Corinthians 2:6-7  We do, however, speak a message of wisdom among the mature, but not the wisdom of this age or of the rulers of this age, who are coming to nothing. No, we declare God's wisdom, a mystery that has been hidden and that God destined for our glory before time began.

should be made known 
1 Peter 1:12  It was revealed to them (the prophets) that they were not serving themselves but you, when they spoke of the things that have now been told you by those who have preached the gospel to you by the Holy Spirit sent from heaven. Even angels long to look into these things.

to the rulers and authorities 
Ephesians 1:21  ... far above all rule and authority, power and dominion and every name that is invoked, not only in the present age but also in the one to come. 
Ephesians 6:12  For our struggle is not against flesh and blood, but against the rulers, against the authorities, against the powers of this dark world and against the spiritual forces of evil in the heavenly realms.
Colossians 2:9-10  For in Christ all the fullness of the Deity lives in bodily form, and in Christ you have been brought to fullness. He is the head over every power and authority.
Colossians 2:15  And having disarmed the powers and authorities, he made a public spectacle of them, triumphing over them by the cross.

in the heavenly realms 
Ephesians 1:3  Praise be to the God and Father of our Lord Jesus Christ, who has blessed us in the heavenly realms with every spiritual blessing in Christ.

according to his eternal purpose that he accomplished in Christ Jesus our Lord 
Ephesians 1:11-12  In him we were also chosen, having been predestined according to the plan of him who works out everything in conformity with the purpose of his will, in order that we, who were the first to put our hope in Christ, might be for the praise of his glory.
