Ephesians 1 KJV
1 Paul, an apostle of Jesus Christ by the will of God, to the saints which are at Ephesus, and to the faithful in Christ Jesus:
2 Grace be to you, and peace, from God our Father, and from the Lord Jesus Christ.
3 Blessed be the God and Father of our Lord Jesus Christ, who hath blessed us with all spiritual blessings in heavenly places in Christ:
4 According as he hath chosen us in him before the foundation of the world, that we should be holy and without blame before him in love:
In that we receive all blessings received "in Christ", and in that to be "in Christ" means that we are recreated:
2 Corinthians 5 KJV
17 Therefore if any man be in Christ, he is a new creature: old things are passed away; behold, all things are become new.
18 And all things are of God, who hath reconciled us to himself by Jesus Christ, and hath given to us the ministry of reconciliation;
Then I conclude that our election, one of those blessings, is received when we are baptized into Christ, even as Jesus was "my servant, whom I uphold; mine elect" (Isaiah 42:1).
So this would be what some call "corporate election". Jesus was Chosen of God, fulfilled the Law and Righteousness, and we receive what was His. Including His election.
Otherwise, we are receiving the greatest blessing of all, being chosen of God, outside of Christ, His choosing bringing us into Christ. But the Bible says we are first in Christ, and in Him we receive everything we receive.
Much love!
Mark
