Thank you for this discussion. Missing from this conversation is Isaiah 53, which clearly depicts Christ as the suffering servant. Starting in verse 8, the text describes an unjust trial that led to an unfair death, though he was buried with criminals.
Yet implicit in the victory described in Luke 53:11, 12 is that this servant is alive after he carried the sins of his people.
After suffering, He will reflect and be satisfied in his finished work (Isaiah 53:11). A dead man cannot do that.
A dead man cannot divide the spoils of victory (Isaiah 53:12). Only a resurrected King can do that.
Isaiah 53:8–12 NET
8 He was led away after an unjust trial—but who even cared? Indeed, he was cut off from the land of the living; because of the rebellion of his own people he was wounded. 9 They intended to bury him with criminals, but he ended up in a rich man’s tomb, because he had committed no violent deeds,nor had he spoken deceitfully. 10 Though the Lord desired to crush him and make him ill, once restitution is made, he will see descendants and enjoy long life, and the Lord’s purpose will be accomplished through him. 11 Having suffered, he will reflect on his work, he will be satisfied when he understands what he has done. “My servant will acquit many, for he carried their sins. 12 So I will assign him a portion with the multitudes, he will divide the spoils of victory with the powerful, because he willingly submitted to death and was numbered with the rebels, when he lifted up the sin of many and intervened on behalf of the rebels.
