Romans 11:33

O, how deep is the richness of God's wisdom and knowledge! How difficult [it is for us] to explain His judgments and how impossible [for us] to accurately track how He operates!

Ephesians 3:10

This was done so that now God's many-sided wisdom could be made known through the church, to the rulers and authorities in the heavenly realms [Note: "Heavenly realms" here refers to the world around us, where these angelic beings (good or bad) view the unfolding of God's wonderful plan],
