The resurrection life is central to Christian experience, but the resurrection life derives its meaning in the completed work of the cross.
From Fleming Rutledge:
What then is the resurrection? It is the vindication of the crucified One. The resurrection doesn’t cancel out the cruciﬁxion as if it were only a passing episode to be noted briefly (or not) on the way to Easter. You here today are blessed because you know, or you have suspected, that Good Friday is not optional. You understand, or you are on your way to understanding that the Day of Resurrection finds its meaning from the cross. The resurrection does not reverse the cruciﬁxion. The resurrection vindicates the cruciﬁxion (vindicate, meaning to verify, conﬁrm, authenticate). The work of Jesus is brought to completion on the cross. That’s what “it is finished” means. The Father and the Son together, in the power of the Spirit, are saying to us, the work that the Father gave the Son to accomplish is consummated, completed, finished as he dies. The saying is just one word in Greek: tetelestai. The Latin is particularly good: consummatum est. So you see, the resurrection does not cancel out the cross. It verifies and conﬁrms that the cross was the main event.
