Some time ago I posted the following quote from Joel Green's commentary on 1 Peter (Grand Rapids: Eerdmans, 2007). I think it's worth posting it again. It is about the resurrection.
Three interrelated motifs help to structure our understanding: (A) Resurrection signals the restoration of Israel. (B) Resurrection marks God's vindication of the righteous who have suffered unjustly; having been condemned and made to suffer among humans, the righteous will in the resurrection be vindicated before God. (C) Resurrection marks the decisive establishment of divine justice; injustice and wickedness will not have the final word, but in the resurrection will be decisively repudiated. To proclaim the resurrection, then, is already to proclaim a new world, and to call for a "conversion of the imagination." (page 28)
I have been thinking that in Acts the apostles' preaching was often about the resurrection (and, of course, the death) of Christ. It's good news for all. But for the poor and oppressed, this is especially comforting, for it is about God's justice and vindication for the suffering righteous. Injustice does not have the final say. God reigns. It is good news indeed.
