Jesus's disciples having denied and betrayed him just three days earlier, now on the night of the resurrection, afraid, suspicious, sitting in darkness, did not believe the report that Jesus rose from the dead. That is when Jesus appeared to them, knowing where they were, seeking them out, no locked door barring him, showing them the nail holes in his hands; and instead of berating them, judging them, or punishing them, declared this reassuring salutation to them, "Peace to you". Consider the depth of his peace and his unconditional grace!
