We do not know how heavy the sin-bearing had to have been, when the full weight of all sin past, present, and future rested on the shoulders of Christ on the cross. Jesus never sinned for he was God in the flesh. Perhaps that is part of the teaching for us that when we feel like crying God, why have you forsaken me , we know that Jesus, in the flesh, cried out something similar. We also know that he was the divine Author of the rest of the story the rest of Psalms 22 which clearly depicts the rest and faith we have in God, who delivers and comforts and cares for us. He does so even in the midst of horrible times when humanly it seems there is no way out.
Some thoughts hope it is of some help.
May God bless you and be with you, Mitch.
