Father, Forgive them

I read Jon Meacham's book, The Hope of Glory.  It is a study of the last seven words/phrases of Christ.

The first chapter is a look at "Father, forgive them; for they know not what they do." His thesis is that while we often use these words as evidence of not only Jesus's forgiveness of those who are executing him, but of all of us - evidence of the forgiving nature of Jesus and therefore God, he (Meacham) doesn't see it that way.

Meacham proposes that "Jesus's death was essential to Christian hope."  He says, "So why does Luke have Jesus seem to be forgiving his tormentors for playing the critical and necessary role in bringing about the salvation few the world and the coming of a kingdom of justice?" I other words (as I see what Meacham is saying), the idea that the death of Christ is essential for God's plan of salvation means that those who perpetrated it are not in need of forgiveness. Does it seem to you that he is proposing that because the death of essential, those who executed Jesus were working in God's plan?

I'm going to leave aside the idea that Jesus's death is essential to Christian hope for just a moment (I think we could have a discussion around that idea, too. I'm troubled by the idea that the executioners do not need forgiveness (because of a lack of sin in this instance) because the death of Jesus was part of God's plan. They didn't kill him because they were motivating by bringing about God's kingdom. They killed him because they were threatened and were seeking to continue their power.  They executed an innocent man - not for any kingdom-bringing purposes. It certainly seems to me that forgiveness was necessary.

In fact, the very idea of their actions demonstrates not a motivation to bring about the kingdom, but evidence of our need (and their need) for grace and forgiveness. If God needed the execution of his son to bring about the salvation of the world (which I have my doubts about), then could it be because we are a people who would commit these acts? I don't think we can ignore the sin when the sin is the reason God needs to intervene.
