I am just going to reply to this part as it is what time allows now...and even to this part I have a long answer, we can discuss the rest later. Now just to be clear.
The religious leaders said "You saved others so why can't you save yourself and come down from the cross and we will believe you" to which you gave two options for interpretation of Jesus's answer, the first which is "you are right, I can't come down because God has forsaken me" which is clearly wrong, I don't know if that's what you think I wrote or you think this is what I meant, which I apologise if you think that is the case because that's not what I meant. Of course Jesus could have come down from the cross, He was completely in charge of the situation. Every single moment He was in charge of the situation. Just to show one example
"Jesus, when he had cried again with a loud voice, yielded up the ghost." (Matthew 27:50) Jesus dismissed His spirit from His body and told it to go to the Father. Even this was in His control and not someone else's. Jesus had everything under control all the time. The cross was no defeat, but the greatest victory mankind has ever known. Jesus is no longer on the cross. He is not the suffering Christ. He is the victorious Christ. - this part I'm sure you agree with.
So then why would Jesus shout 'My God, my God, why have you forsaken me'? Because God Father has forsaken God Son. The
why, it seems to me, is not a question looking for an answer, but a way of expressing the horrors of abandonment.
Jesus knew ahead of time what he was doing and what would happen to him and why he was doing it. His Father had sent him for this. This very moment. And he had agreed to come, knowing all that would happen.
“Then Jesus, knowing all that would happen to him, came forward and said to them, ‘Whom do you seek?’” (
John 18:4). He gave himself up. So he knew. He knew it was coming. He knew everything.
The
why is a moment of agony, not theological curiosity. The moment was one of agony.
the fact that he is not asking a question so much as expressing a horror is that the words are a reflex of immersion in Psalm 22, it seems. They are a direct quotation. But when you are hanging on the cross you don’t say: “Oh, I think I am going to quote some Scripture here.”
It either is in you as the very essence of your messianic calling or it is not. And if it is in you, then you give vent at the worst moment of your life with the appointment of your Father scripted in Psalm 22. That seems to be right at the heart of what is going on.
Jesus did not die as a martyr to a righteous cause or simply as an innocent man wrongly accused and condemned. Nor, as some suggest, did He die as a heroic gesture against man’s inhumanity to man. The Father could have looked favorably on such selfless deaths as those. But because Jesus died as a substitute sacrifice for the sins of the world, the righteous heavenly Father had to judge Him fully according to that sin.
The Father forsook the Son because the Son took upon Himself “our transgressions, … our iniquities” (
Isa. 53:5). Jesus “was delivered up because of our transgression” (
Rom. 4:25) and “died for our sins according to the Scriptures” (
1 Cor. 15:3). He “who knew no sin [became] sin on our behalf” (
2 Cor. 5:21) and became “a curse for us” (
Gal. 3:13). “He Himself bore our sins in His body on the cross” (
1 Pet. 2:24), “died for sins once for all, the just for the unjust” (
1 Pet. 3:18), and became “the propitiation for our sins” (
1 John 4:10).
So why did Jesus say God and not the Father?
When Christ was forsaken by the Father, their separation was not one of nature, essence, or substance. Christ did not in any sense or degree cease to exist as God or as a member of the Trinity. He did not cease to be the Son, any more than a child who sins severely against his human father ceases to be his child. But Jesus did for a while cease to know the intimacy of fellowship with His heavenly Father, just as a disobedient child ceases for a while to have intimate, normal, loving fellowship with his human father.
By the incarnation itself there already had been a partial separation. Because Jesus had been separated from His divine glory and from face-to-face communication with the Father, refusing to hold on to those divine privileges for His own sake (
Phil 2:6).
I don't know how much more can I explain my self. But please answer to all of the above if you can, what you agree with or disagree with. I'm not sure I can write more on this topic.
