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,
Ephesians 3 v 10
Manifold = Many faceted
If you have a large diamond with lots of facets on it, it will twinkle marvellously.
God has made us different because God is multi-faceted and wants to portrays his qualities in many different people. So he has put his wisdom in me in one way and in Anna my wife in another way.
