“Yahweh’s speeches are intended not to give Job an answer to the question of why he suffers but to re-establish the proper relationship between God and his human creature. Job has sought God to accuse him of injustice (40:8), but God, through a display of his power and wisdom, brings Job to the point where he “repents” (42:1-6). He no longer seeks an answer to the question of his suffering: he simply bends the knee to God in submission.”
