¹⁰ so that through the church the manifold wisdom of God might now be made known to the rulers and authorities in the heavenly places.
Ephesians 4:10 ESV 

I read somewhere that Ephesians was the Mt. Everest of New Testament theology.  That its content and mysteries contained within were worthy of a lifetime of study.  I am beginning to believe it.

First, Paul's sentence structure is very complex.  Just to digest the simplest of ideas often requires two or three rereads of a passage.  Then a passage like today's verse enters the picture.  

I have searched several commentaries and still have the following questions.

1.  Who are the "rulers and authorities in heavenly places" to which Paul refers?

2.  If they are already seated in heavenly placed, how is it the church can reveal anything to them (whoever they are)?

Please jump in with answers.
