Moses told the people of Israel before they entered the Promised Land that the reason God was driving out the inhabitants of the land before them was because of their abominable practices (Deuteronomy 18:12). The Israelites were warned not to learn to follow the abominable practices of those nations (Deuteronomy 18:9), but to “be perfect with the LORD thy God” (Deuteronomy 18:13, KJV). The Hebrew word that is translated perfect, tamiym (taw-meemˊ) was “used of one’s relationship with another person (Judges 9:19; Proverbs 28:18; Amos 5:10); and of one’s relationship with God (Genesis 17:1; Deuteronomy 18:13; 2 Samuel 22:24, 26). Moreover, this word described the blamelessness of God’s way, knowledge, and Law (2 Samuel 22:31; Job 37:16; Psalm 19:7[8])” (H8549). Tamiym is derived from the word tamam (taw-mamˊ) which means “to complete…At its root, this word carries the connotation of finishing or bringing closure” (H8552). Another word that is derived from tamam is the Hebrew word tam (tawm), which also means complete. Tam is “an adjective meaning integrity, completeness. This is a rare, almost exclusively poetic term often translated perfect but not carrying the sense of totally free from fault, for it was used of quite flawed people” (H8535). One of the people described by tam is Job. It says in Job 1:1, “There was a man in the land of Uz, whose name was Job; and that man was perfect and upright.”

Job is believed to have lived during the time of the Patriarchs, Abraham, Isaac, and Jacob because of the length of his life (Job 42:16). “The fact that Job acted as the priest for his family (Job 1:5) implies that the Mosaic Law had not yet been given” (Introduction to Job). Job had seven sons and three daughters and was considered the greatest of all the people of the east (Job 1:2-3). It says in Job 1:4-5, “His sons used to go and hold a feast in the house of each one on his day, and they would invite their three sisters to eat and drink with them. And when the days of the feast had run their course, Job would send and consecrate them, and he would rise early in the morning and offer burnt offerings according to the number of them all. For Job said, ‘It may be that my children have sinned and cursed God in their hearts.’ Thus Job did continually.”

Job’s reputation as a perfect man was not only acknowledged on earth, but also in heaven. God told Satan there was no one like Job on the earth, “a blameless and upright man, who fears God and turns away from evil” (Job 1:8). Because Satan challenged Job’s reputation, God allowed Satan to test Job. It says in Job 1:9-12:

Then Satan answered the Lord and said, “Does Job fear God for no reason? Have you not put a hedge around him and his house and all that he has, on every side? You have blessed the work of his hands, and his possessions have increased in the land. But stretch out your hand and touch all that he has, and he will curse you to your face.” And the Lord said to Satan, “Behold, all that he has is in your hand. Only against him do not stretch out your hand.” So Satan went out from the presence of the Lord.

“Satan’s question ‘Does Job fear God for no reason?’ challenged the motive behind Job’s reverence for God. Satan claimed that Job lived as he did because God had blessed him. This was not the case, for Job reverenced the LORD sincerely. God’s purpose in allowing these trials to come on Job was to purify and strengthen Job’s faith in him” (note on Job 1:9-12).

The Apostle Peter, of whom Jesus said, “Satan has demanded to have you, that he might sift you like wheat” (Luke 22:31), wrote about the various trials that Christians must go through. Peter said trials occur, “so that the tested genuineness of your faith—more precious than gold that perishes though it is tested by fire—may be found to result in praise and glory and honor at the revelation of Jesus Christ” (1 Peter 1:7). Peter talked about suffering as a Christian and told believers, “Beloved, do not be surprised at the fiery trial when it comes upon you to test you, as though something strange were happening to you. But rejoice insofar as you share Christ’s sufferings, that you may also rejoice and be glad when his glory is revealed” (1 Peter 4:12-13). Peter also warned believers about Satan’s tactics. Peter said we must, “be soberminded; be watchful,” because “your adversary the devil prowls around like a roaring lion, seeking someone to devour,” and then he, instructed believers to, “resist him, firm in your faith, knowing that the same kinds of suffering are being experienced by your brotherhood throughout the world” (1 Peter 5:8-9).

Jesus reiterated and affirmed the standard of perfection that was established by Moses. Jesus explained to his disciples, “You have heard it said, ‘You shall love your neighbor and hate your enemy.’ But I say to you, Lover your enemies and pray for those who persecute you, so that you may be sons of your Father who is in heaven. For he makes the sun rise on the evil and the good, and sends rain on the just and the unjust. For if you love those who love you, what reward do you have? Do not even the tax collectors do the same? And if you greet only your brothers, what more are you doing than others? Do not even the Gentiles do the same? You therefore must be perfect, as your heavenly Father is perfect” (Matthew 5:43-48). Jesus used the Greek word teleios (telˊ-i-os) figuratively in a moral sense to refer to us being perfect as God is perfect. Like tamiyn in the Old Testament, teleios means “complete” and is used “specifically of persons meaning full age, adulthood, full-grown. In the NT, figuratively meaning full-grown in mind and understanding (1 Corinthians 14:10); in knowledge of the truth (1 Corinthians 2:6; 13:10; Philippians 3:15; Hebrews 5:14); in Christian faith and virtue (Ephesians 4:13)” (G5046).

A word that is derived from teleios is teleioo (tel-i-oˊ-o). Jesus used the Greek word teleioo when he told his Father, “I glorified you on earth, having accomplished the work that you gave me to do” (John 17:4). The King James Version of the Bible translates the word teleioo in John 17:4 as finished and the New Living Translation states, “I brought glory to you here on earth by completing the work you gave me to do” (John 17:4). Another word that helps us to understand what it means to be perfect is telos (telˊ-os), which means, “(to set out for a definite point or goal); properly the point aimed at as a limit, i.e. (by implication) the conclusion of an act or state” (G5056). Jesus used the word telos when he said, “you will be hated by all for my name’s sake. But the one who endures to the end will be saved” (Matthew 10:22).

Satan’s attempt to break Job involved him taking away everything that Job had in one fell swoop. Job 1:13-22 tells us:

One day when Job’s sons and daughters were feasting at the oldest brother’s house, a messenger arrived at Job’s home with this news: “Your oxen were plowing, with the donkeys feeding beside them, when the Sabeans raided us. They stole all the animals and killed all the farmhands. I am the only one who escaped to tell you.”

While he was still speaking, another messenger arrived with this news: “The fire of God has fallen from heaven and burned up your sheep and all the shepherds. I am the only one who escaped to tell you.”

While he was still speaking, a third messenger arrived with this news: “Three bands of Chaldean raiders have stolen your camels and killed your servants. I am the only one who escaped to tell you.”

While he was still speaking, another messenger arrived with this news: “Your sons and daughters were feasting in their oldest brother’s home. Suddenly, a powerful wind swept in from the wilderness and hit the house on all sides. The house collapsed, and all your children are dead. I am the only one who escaped to tell you.”

Job stood up and tore his robe in grief. Then he shaved his head and fell to the ground to worship. He said,

“I came naked from my mother’s womb,
    and I will be naked when I leave.
The Lord gave me what I had,
    and the Lord has taken it away.
Praise the name of the Lord!”

In all of this, Job did not sin by blaming God. (NLT)

The phrase ‘while he was still speaking’ “indicates that all the events took place one right after the other. This afforded Job no opportunity to prepare himself or regain his composure and made each one harder to bear” (note on Job 1:16-18), and yet; we are told that Job made it through this experience without sinning against God.

Job’s story continues with Satan making a second accusation against Job and God giving him another opportunity to test Job’s faith. Satan struck Job with loathsome sores from the sole of his foot to the crown of his head (Job 2:7). “Job’s sores may have disfigured him so badly that he could barely be recognized by his friends. They shared in his sorrow (Job 2:12, 13) but did not understand that affliction does not always signify punishment (see John 9:3). Much of what they said in their conversation with Job (chs 4-37) was true but was misapplied to Job’s situation. They did not recognize  that God was testing Job and instead assumed that Job’s suffering was proportionate to some sin he had committed. It may even be that they were unknowingly used by Satan in his attempt to cause Job to sin” (note on Job 2:11-13). Job’s friend Bildad thought that he needed to repent (Job 8:5). “Job responded to Bildad’s reasoning by declaring that no man is righteous in God’s sight (Job 9:2, 20) or able to dispute with him (Job 9:3, 14). Job did not claim to be perfect but recognized his need for God’s mercy (Job 9:15) (note on Job 9:1-10:22). Job said about God:

Though I am in the right, I cannot answer him;
    I must appeal for mercy to my accuser.
If I summoned him and he answered me,
    I would not believe that he was listening to my voice.
For he crushes me with a tempest
    and multiplies my wounds without cause;
he will not let me get my breath,
    but fills me with bitterness.
If it is a contest of strength, behold, he is mighty!
    If it is a matter of justice, who can summon him?
Though I am in the right, my own mouth would condemn me;
    though I am blameless, he would prove me perverse. (Job 9:15-20)

Job understood that he could not claim to be a perfect man based on his own merit. The burnt offerings that Job made for his children (Job 1:5), and likely for himself on other occasions, did not justify him in God’s sight. Romans 3:20 tells us, “For by the works of the law no human being will be justified in his sight, since through the law comes knowledge of sin.” Job realized he needed God’s mercy because as it says in Romans 3:23-25, “all have sinned and fall short of the glory of God, and are justified by his grace as a gift, through the redemption that is in Christ Jesus, whom God put forward as a propitiation by his blood, to be received by faith.”
