In the ancient Hebrew, the word we have for righteousness and justice is sedeq, which most literally means right order. The idea is that when things are as they were intended to be by God, then the poor will be taken care of, nobody’s rights will be trampled on, and God’s grace will be evident in every situation. So this idea of sedeq is of course a frequently-mentioned topic in the prophets’ preaching. Today we have the prophet Jeremiah pointing out the lack of sedeq in the community of the Israelites: “for they broke my covenant,” Jeremiah prophecies, “and I had to show myself their master, says the LORD.”
There is just one possible antidote to the infidelity of the people, and that is God’s loving-kindness. The Hebrew language has a word for this, too, and that is hesed. It is summed up in the way the Lord wishes to bring the people back into right relationship as Jeremiah says: “But this is the covenant that I will make with the house of Israel after those days, says the LORD. I will place my law within them, and write it upon their hearts; I will be their God, and they shall be my people.”
The hesed that Jesus brings is still more radical, and that turns out to be a problem for Peter. He knows well enough who Jesus is: “You are the Christ, the Son of the living God.” But when it turns out that the way for Jesus to make all that happen and unleash God’s ultimate loving-kindness is for Jesus to die, that doesn’t set well with Peter. “God forbid, Lord! No such thing shall ever happen to you.”
The thing is, for hesed to happen in any situation, someone pretty much always has to lay down their life. It might be physically as Jesus did on the cross, but it could also be by letting a disagreement go, pursuing forgiveness even at the cost of being right about something on principle, or giving up one’s own desires so that others can be nourished. And Satan knows that hesed is the worst thing in the world that can happen for him. So he always wants us to say “God forbid, Lord! Why should you have to die? Why should I have to die?” But we have to put such thoughts aside. We have to think as God does, not as human beings do.
