Ephesians 3:10, "To the intent that now unto the principalities and powers in heavenly places might be known by the church the manifold wisdom of God"
God is revealing himself and his plans through the lowly church on earth. This is an amazing fact that we are somehow being used by God to reveal who is to these principalities and powers in heavenly places. God is demonstrating his wisdom through lowly, humble Christians on earth. Amazing grace!
Angels are interested in God's relationship with man, especially with those in the church who are saved and inherit salvation. 1 Peter 1:12.
Father God, you have put the church on display as a trophy of your grace and mercy. Thank you, Lord, for the gospel that Christ died for our sins, he was buried, and he rose again on the third day. The Lord Jesus spoiled principalities and powers and made a shew of them openly, triumphing over them in it. Amen.
