Okay. I can live with that.
I believe the strongest of all the verses and context is found in Hebrews 9:12 where Paul focuses in on Christ being the supreme sacrifice for sin.
"Neither by the blood of goats or calves, but
by his own blood he (Jesus) entered in
once into the holy place, having
obtained eternal redemption for us". The two words,
"for us", are not in the original. "Having obtained
in himself eternal redemption." In Philippians 2:8 its even more expressive "He became obedient unto death, even the death of the cross.
Wherefore God also hath highly exalted him." I think you will see the issue here with the Trinity as one who holds such teaching must say Christ did not benefit from his own death and was exalted by reason of his submission. My view, which is supported by the above verses, is that Jesus, in saving us, was also saved...not in a sense of him needing saving from sin, but saved from death itself. I believe its on this basis God's righteousness was rightly declared on our nature as per Romans 3:25.
Note on Hebrews 9:12 "obtained; secured"
tn This verb occurs in the Greek middle voice, which here intensifies the role of the subject, Christ, in accomplishing the action: “he alone secured”; “he and no other secured.”
