The Eternal Purpose of God is that the Church would put the multifarious wisdom of God on display before the angels. Whenever God moves, His move is deep.
He is accomplishing so much at once in the unfolding and revealing of Himself by sending His Son, who was “made the seed of David according to the flesh and declared to be the Son of God with power according to the Spirit of Holiness by the resurrection from the dead.
"To the intent that now unto the principalities and powers in heavenly places might be known by the church the manifold wisdom of God." Ephesians 3:10
Remember, we are talking about the Seed of David. As the Seed of the Woman, the Seed of Abraham, and the Seed of David, He is the heir of all the promises and the representative of the Human Race before God. He is the One with all authority. As the Last Adam, He is the “federal Head” of the Human Race, the representative of the Human race and the rightful Heir to every covenant God ever made with man.
Before Christ died, He was the rightful heir of God’s creation as a man. Then He offered Himself up in death. No one took His life, but He gave it for us.
No man taketh it from me, but I lay it down of myself. I have power to lay it down, and I have power to take it again. This commandment have I received of my Father." John 10:18
Then God raised this Man from the dead and seated Him at His Right Hand. This Man was declared to be the Son of God with power. The Greek word for declaration there means “to designate.”
