Ephesians 3:10-12

So now through the church the multifaceted wisdom of God [in all its countless aspects] might now be made known [revealing the mystery] to the [angelic] rulers and authorities in the heavenly places. This is in accordance with [the terms of] the eternal purpose which He carried out in Christ Jesus our Lord, in whom we have boldness and confident access through faith in Him [that is, our faith gives us sufficient courage to freely and openly approach God through Christ].
