His spiritual alienation on the cross made him fully man, devoid of divinity, forsaken, just as lost and hopeless as any other man. He became a curse. He became sin (2 Cor 5:21). This alienation was in the plans; in reciting a prophecy about himself, Jesus said that he had come to pour his soul out to death (Lk 22:37; cf. Is 53:12). He had to die in Spirit to meet mankind where mankind resided.
Like David in his twenty-second Psalm, Jesus was a man without the Father. He called out not to his Father, but to God. He was a curse, though not physically, unless we say that God erred in His creation of nature. He was not accursed before his crucifixion; he was not a curse in body. On that cross, when he bore the sins of Israel, he was a spiritual curse. But then, as with David, the estrangement from God ended. “Father, into your hands I commit my spirit!” he proclaimed as he drew his last breath (Lk 23:46).
