Job 9:32-33 arises from Job's anguish over the immense distance between himself and God. Job recognizes that God is not a human opponent whom he can summon into court on equal terms, and he longs for an arbiter or mediator who could stand between them and "lay his hand" upon both. In the immediate context, Job is expressing a desperate need rather than giving a formal prediction of a future Messiah. He desires someone capable of bridging the gulf between a mortal man and the sovereign God.
First Timothy 2:5 provides the Christian answer to that longing: "there is one God, and there is one mediator between God and men, the man Christ Jesus." The correspondence is especially meaningful because the New Testament presents Christ as uniquely qualified to reconcile humanity to God. Christians therefore read Job's cry as an anticipation of a need ultimately met in Jesus. Job does not name or explicitly foresee Christ in this passage, but the mediator he longs for becomes a powerful Old Testament pattern of the role Christ fulfills perfectly as the One who brings sinful human beings into reconciliation with God.
