Job is not finished. In Job 13:13-19 Job utters what amounts to a confession of faith,
“Keep silent and let me speak; then let come to me what may. Why do I put myself in jeopardy and take my life in my hands? Though he slay me, yet will I hope in him; I will surely defend my ways to his face. Indeed, this will turn out for my deliverance, for no godless man would dare come before him! Listen carefully to my words; let your ears take in what I say. Now that I have prepared my case, I know I will be vindicated. Can anyone bring charges against me? If so, I will be silent and die.”
The corner has been turned. Job wants to speak in his defense. He will plead his case no matter what will come as a result. He knows that even if YHWH strikes him dead, he will be vindicated in the end. With these words, Job points us ahead to Jesus Christ, who prayed a similar prayer in Gethsemane:
“My soul is overwhelmed with sorrow to the point of death. . . . He fell with his face to the ground and prayed, `My Father, if it is possible, may this cup be taken from me. Yet not as I will, but as you will. . . .The spirit is willing, but the body is weak. My Father, if it is not possible for this cup to be taken away unless I drink it, may your will be done.”
Jesus knew that in dying, he too, would be vindicated. Jesus must drink the cup of wrath for salvation to come to God’s people. As the greater Job, Jesus is willing to be slain, knowing he would be vindicated in the end.
