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: 5 Having predestinated us unto the adoption of children by Jesus Christ.
Ephesians 1:3–5.
Yes, we were all in Christ during the crucifixion. Jesus gave birth to his offspring only after the crucifixion. No one was born-again until the water and the blood poured from Jesus on the cross.
Jesus is the tree of soul life. All the fruit was in him when he hung on the cross. I was in him when he hung on the cross. Paul was in him when he hung on the cross. And it's the cross that makes it possible for us to realize who our mother is. Jesus is our mother, brother, father, sister, aunt, and uncle.
John
