The question is not, what can God say about evil, but, what can God do about evil?
“If you want to understand God’s justice in an unjust world, says [Isaiah], this is where you must look. God’s justice is not simply a blind dispensing of rewards for the virtuous and punishment for the wicked, though plenty of those are to be found on the way. God’s justice is a saving, healing, restorative justice, because the God to whom justice belongs is the Creator God who has yet to complete his original plan for creation and whose justice is designed not simply to restore balance to a world out of kilter but to bring to glorious completion and fruition the creation, teeming with life and possibility, that he made in the first place. And he remains implacably determined to complete this project through his image-bearing human creatures and, more specifically, through the family of Abraham,” (Wright, Evil And The Justice of God, 64).
But how? Well the story of redemption and rescue is most certainly focused on the Servant, YHWH’s Servant.
“Central to the OT picture of God’s justice in an unjust world, then, is the picture of God’s faithfulness to unfaithful Israel. And central to that picture is the picture of YHWH’s Servant, an individual who stands over against Israel and takes Israel’s fate upon himself so that Israel may be rescued from exile, allowing the human race at last to proceed, as in Isaiah 55, toward the new creation, in which thorns and thistles will be replaced by cypress and myrtle, dust and death by fresh water and new life,” (Wright, 65).
Grace and peace.
