Stephen Pegler, Trinity Journal 23.2 (2002), page 278:

Easter Saturday is the boundary between Good Friday and Resurrection Sunday and we should be struck by how utterly dismal everything would be for those who experienced it. Jesus is dead, his message and person discredited. The kingdoms of this world have won, and the God Jesus trusted is to be seen either as having failed Jesus or as ultimately powerless against sin and death. Only against this depressing background can we truly understand the glorious reversal and vindication of Jesus’ person, his ministry, and the God in whom he trusted.
