Abraham was not placed in Christ when he believed.
Only the Bride of Christ is placed in Christ when (during the church age) someone believes in Christ.
We become like Eve's body was in Adam's body, before God removed bone and flesh to reveal her to Adam.
Right now we are IN HIM, seated with Him in heavenly places!
At the resurrection, he can look at us and say in a way similar to what Adam said when he first saw the woman...
"Now! This is my Bride! She is bone of my bones, and glorious flesh of my glorious flesh!"
Yup... That is why we in our resurrection bodies will be called His Bride!
In the meanwhile?
Our
'old man' bodies have been crucified with Christ!
Galatians 2:20
I have been crucified with Christ and I no longer live, but Christ lives in me.
The life I now live in the body, I live by faith in the Son of God, who loved me
and gave himself for me."
Grace and peace!
