Making known to us the mystery of his will, according to his purpose, which he set forth in Christ as a plan for the fullness of time, to unite all things in him, things in heaven and things on earth. – Ephesians 1:9-10
This is the beginning of the purposes of the redemption “we have” (Eph 1:7). The revealing of God’s mystery is a portion of our salvation. The church is working out the mystery of the will of God. It is not lost that this is all purpose in the sending forth of Christ as propitiation and blood (Rom 3:25).
The descriptive language of the final eschaton always exceeds the “elect”. It transcends to the fullness of all of creation. The fullness of history is found in union with Christ. This union with Him is the fulfillment of Christian baptism (Rom 6:3-5).
