Jesus in Job? Many people would think it's impossible to find Jesus in that Old Testament book, but the contrary is true.
Job was a righteous man, one of a kind, in the generation he was living in. He was very rich - actually the wealthiest man in his area (Job 1:3). Yet, we see how he was literarily made "naked" when everything he had was destroyed and his own life was fading away. He knew this was God's plan and therefore he accepted it without blaming or cursing God (Job 1:20-22).
Now this is a perfect picture of Jesus, the richest King in the Universe, becoming "naked" of His Royalty, coming down as man and enduring the Cross, even unto death, to fulfill God's plan:
"Let this mind be in you, which was also in Christ Jesus: Who, being in the form of God, thought it not robbery to be equal with God: But made himself of no reputation, and took upon him the form of a servant, and was made in the likeness of men: And being found in fashion as a man, he humbled himself, and became obedient unto death, even the death of the cross." (Philippians 2:5-8)
Well, because of the negative influence of his "friends", Job finally gave up searching for the righteous cause of his sufferings and God had to intervene.
Jesus, of course, did not fall for that, but the symbol remains, because it was so difficult for our Lord too, that He had to say:
"My God, My God, why have You forsaken me?" (Mark 15:34)
Finally, we can not but overlook the Priestly function of Job. When he was restored, the Lord turned to his friends and said:
"And it was so, that after the LORD had spoken these words unto Job, the LORD said to Eliphaz the Temanite, My wrath is kindled against thee, and against thy two friends: for ye have not spoken of me the thing that is right, as my servant Job hath. Therefore take unto you now seven bullocks and seven rams, and go to my servant Job, and offer up for yourselves a burnt offering; and my servant Job shall pray for you: for him will I accept: lest I deal with you after your folly, in that ye have not spoken of me the thing which is right, like my servant Job."
Job became an intercessor on their behalf, as Jesus "...ever liveth to make intercession for them" (Hebrews 7:25)
