The church is the object mentioned here. Since it has a great election, it is evident that the members are then a part of the election. This was in the plan of God before the ages began, before the overthrow. Adoption or placing as sons. No more are children spoken of.
Adoption means coming to age.
Those who have life become mature and are placed in the body, the church. Accepted in the Beloved. This means that the members are highly favored. The word is used here and where Mary was said to be highly favored. Being in Christ gives this acceptance and favor.
