It is in Christ God finds an accurate and complete expression of himself, in a human body (100% God in human form). Jesus mirrors our completeness and endorses our true identity. He is ” I am” in us. You were in Christ when he died which means that his death represents your true circumcision. Sin’s authority in the human body was stripped off you in dying your death. (GLORY) In the same parallel (your co-circumcision in his death) yiur co-burial and joint resurrection is now demonstrated in baptism; your co-inclusion in Christ is what God’s faith knew when he powerfully raised him from the dead.
I am identified in him by him and he is the I am in me.
