The question of whether there exists similarity between God and Man appears to be of some great concern to you. The story of creation in Genesis lays the foundation for all that follows.
In Genesis 1, on the sixth day of creation, we have this:
26 Then God said, “Let us make mankind in our image, in our likeness,
so that they may rule over the fish in the sea and the birds in the sky,
over the livestock and all the wild animals, and over all the creatures
that move along the ground.”
27 So God created mankind in his own image,
in the image of God he created them;
male and female he created them.
The possibility of God taking on a human form is found in those verses. Because God made mankind in His image, such a form is capable of holding God's spirit and showing forth His glory undiminished.
Mankind (through Adam and Eve) sinned and marred the image of God inside them, but Jesus, through the Virgin birth when Mary (or Maryam) conceived by the Holy Spirit, has an unfallen human nature, which therefore has an unmarred image of God.
When the Prophet Job suffered, he not only cried out to God for a savior, he did something more. Chapter by chapter, Job created a Job description for a savior. He listed every quality such a savior must have, and the principle actions that such a savior must perform in order to rescue him from sin, sickness, mortality and his terror of God.
In Job 6:8-10, Job places his hope in the Word of God, as the Apostle John would later call Jesus in John 1. Jesus, the eternal, uncreated word of God.
In Job 9, Job declares that he needs someone powerful like God to save him, but also someone like a man who can sympathize with him and not terrify him. There are four verses in this chapter that point to Jesus walking on water, a sign of divinity. This points to the incarnation, when God comes forth as both God and man in the form of Jesus.
In Job 13:15-16, "though he slay me, I will hope in him", corresponds to baptism, in which we are buried with Christ so that we may rise with him. At baptism, Jesus was annointed as savior, and here Job declares his hope in a savior.
In Job 14:13-17, he speaks of his renewal, his healing and forgiveness. The core of Jesus' ministry was healing people as a sign of their forgiveness from sins.
In Job 17:3-5; 33:22-26, you can see descriptions of the betrayal of Jesus at Gethsemane, such as "He who informs against his friends to get a share of their property" as a reference to Judas.
In Job 17:13-16; 33:27-39, 38:17, you have a detailed description of many events that occurred at the crucifixion of Jesus, such as people piercing him and him making a covenant.
In Job 19:23-27, you have Job's powerful testimony of faith:
“Oh that my words were written!
Oh that they were inscribed in a book!
24 Oh that with an iron pen and lead
they were engraved in the rock forever!
25 For I know that my Redeemer lives,
and at the last he will stand upon the earth.
26 And after my skin has been thus destroyed,
yet in my flesh I shall see God,
27 whom I shall see for myself,
and my eyes shall behold, and not another.
My heart faints within me!
This speaks of the resurrection from the dead.
In Job 21:31, Job speaks extensively about the need for God to exercise judgment against the wicked. This corresponds to the Second Coming of Christ, when "he will come to judge the quick and the dead".
In Job 23:10-14, Job speaks of how he will be perfected, made like pure gold.
But he knows the way that I take;
when he has tried me, I shall come out as gold.
11 My foot has held fast to his steps;
I have kept his way and have not turned aside.
12 I have not departed from the commandment of his lips;
I have treasured the words of his mouth more than my portion of food.
13 But he is unchangeable, and who can turn him back?
What he desires, that he does.
14 For he will complete what he appoints for me,
and many such things are in his mind.
All Christians believe that when Jesus returns, we will be changed and made perfect.
So Job describes what he needs in a savior, his job description. What does God say to this?
7 After the Lord had spoken these words to Job, the Lord said to
Eliphaz the Temanite: “My anger burns against you and against your two
friends, for you have not spoken of me what is right, as my servant
Job has. 8 Now therefore take seven bulls and seven rams and go to my
servant Job and offer up a burnt offering for yourselves. And my
servant Job shall pray for you, for I will accept his prayer not to
deal with you according to your folly. For you have not spoken of me
what is right, as my servant Job has.” 9 So Eliphaz the Temanite and
Bildad the Shuhite and Zophar the Naamathite went and did what the
Lord had told them, and the Lord accepted Job's prayer.
God agreed with Job's request, agreed that what Job needed from God was correct.
The three friends said many wrong things, but here is the place where Bildad sums up their entire argument:
“Dominion and fear are with God;
he makes peace in his high heaven.
3 Is there any number to his armies?
Upon whom does his light not arise?
4 How then can man be in the right before God?
How can he who is born of woman be pure?
5 Behold, even the moon is not bright,
and the stars are not pure in his eyes;
6 how much less man, who is a maggot,
and the son of man, who is a worm!”
The last line is the kicker: Bildad ridicules Job for trusting in "the son of man". He denies that a man "born of woman" can save anyone. Bildad denies that God can become a man.
And God said that Bildad was wrong.
This speech of God to Job is unique. It is God's longest speech in the Bible to any person. At the end, God grants Job the authority to pronounce forgiveness on his friends, unprecedented in history.
Above I gave nine instances where Job either declared what he needed in a savior or described prophetically the actions to be taken by such a savior. This is where it gets interesting. Those nine instances point to nine events in the life and ministry of Christ. They were prophesied 1,700 yers before Jesus was born. AND THEY WERE SPOKEN BY JOB IN CHRONOLOGICAL ORDER! The odds of that happening by chance are 9! to one. That is nine factorial to one, or one chance in 362,880.
To sum up:
- In creation, God made humans in His image, meaning that the image of a human is capable of representing God if he chooses.
- Job listed the essential characteristics and actions of a savior.
- Those characteristics match Jesus and no one else in history.
- God endorsed Job's statements.
- God condemned the friend's statements, including the idea that the savior could not be a "son of man".
- Jesus was born and fulfilled all of Job's prophecies, as well as the prophecies of many prophets since then.
My argument has been brief. For a more detailed exegesis of the verses I have cited to back my argument, see my book Job Rises: Thirteen Keys to a Resilient Life.
