The Bible, in lifting the veil to give a glimpse into heavenly affairs, reveals that Satan later as a rival god appeared before Jehovah in heaven, challenging Jehovah to His face, saying that he could turn God’s servant Job, and by implication any servant of God, away from Him. He charged God, in effect, with unrighteously giving Job everything, along with full protection, so that he, Satan, could not test Job and show what was really in his heart, which, Satan intimated, was bad. He implied that Job served God primarily for selfish considerations. Satan made this point of his argument clear when he said: “Skin in behalf of skin, and everything that a man has he will give in behalf of his soul. For a change, thrust out your hand, please, and touch as far as his bone and his flesh and see whether he will not curse you to your very face.”​—Job 1:6-12; 2:1-7; see SOVEREIGNTY.

In this special case, Jehovah allowed Satan to bring calamity upon Job by not interfering when Satan brought about a raid from Sabean marauders as well as destruction of flocks and shepherds by what Job’s messenger called “the very fire of God” from the heavens; whether this was lightning or other fire is not stated. Satan also brought a raid by three bands of Chaldeans, as well as a windstorm. These things caused the death of all of Job’s children and destroyed his property. Finally, Satan inflicted a loathsome disease upon Job himself.​—Job 1:13-19; 2:7, 8.

These things reveal the might and power of the spirit creature Satan, as well as his vicious, murderous attitude.

It is important to note, however, that Satan recognized his impotence in the face of God’s express command, for he did not challenge God’s power and authority when God restricted him from taking Job’s life.​—Job 2:6.

Continued Opposition to God. By his challenge of God and his charging God’s servants with lack of integrity, Satan lived up to his title “Devil,” meaning “Slanderer,” which title he deserved for having slandered Jehovah God in the garden of Eden.

After his baptism, Satan approached Jesus in the wilderness with three different strong temptations, thoroughly testing him on the issue of devotion to Jehovah. In one of his appeals Satan showed Jesus all the kingdoms of the world, claiming them to be his own. Jesus did not contradict this claim. Nonetheless, Jesus refused to contemplate even for the briefest instant of time any “shortcut” to kingship, nor did he consider for an instant the doing of anything merely to please himself. His immediate reply to Satan was, “Go away, Satan! For it is written, ‘It is Jehovah your God you must worship, and it is to him alone you must render sacred service.’” At this, “the Devil . . . retired from him until another convenient time.” (Mt 4:1-11; Lu 4:13) This illustrates the truth of James’ words later written: “Oppose the Devil, and he will flee from you.”​—Jas 4:7.

Jesus was ever alert to the danger of Satan’s machinations and to the fact that Satan desired to cause his destruction by getting him to entertain a thought contrary to Jehovah’s will. This was demonstrated when Peter, on one occasion, though with good intentions, was actually throwing temptation in his way. Jesus had spoken of the suffering and death he was to undergo. “At this Peter took him aside and commenced rebuking him, saying: ‘Be kind to yourself, Lord; you will not have this destiny at all.’ But, turning his back, he said to Peter: ‘Get behind me, Satan! You are a stumbling block to me, because you think, not God’s thoughts, but those of men.’”​—Mt 16:21-23.

Throughout Jesus’ ministry he was in danger; Satan used human agents to oppose Jesus, trying either to cause him to stumble or to kill him. At one time the people were about to seize Jesus to make him king. But he would not consider such a thing; he would accept kingship only in God’s time and way. (Joh 6:15) On another occasion those of his own hometown attempted to kill him. (Lu 4:22-30) He was constantly harassed by those whom Satan used to try to trap him. (Mt 22:15) But in all of Satan’s efforts, he failed to cause Jesus to sin in the slightest thought or deed. Satan was thoroughly proved to be a liar, and he failed in his challenge of God’s sovereignty and the integrity of God’s servants. As Jesus said, shortly before his death: “Now there is a judging of this world; now the ruler of this world will be cast out”​—completely discredited. (Joh 12:31) Satan had a grip on all mankind through sin. But, knowing that Satan would soon bring about his death, Jesus, after celebrating his last Passover with his disciples, could say: “The ruler of the world is coming. And he has no hold on me.”​—Joh 14:30.

A few hours later, Satan succeeded in having Jesus put to death, first getting control of one of Jesus’ apostles, then using the Jewish leaders and the Roman World Power to execute Jesus in a painful and ignominious manner. (Lu 22:3; Joh 13:26, 27; chaps 18, 19) Here Satan acted as “the one having the means to cause death, that is, the Devil.” (Heb 2:14; Lu 22:53) But in this Satan failed to promote his cause; he only unwillingly fulfilled prophecy, which required that Jesus die as a sacrifice. The death of Jesus in blamelessness provided the ransom price for humankind, and by his death (and subsequent resurrection by God) Jesus could now help sinful humankind to escape from the grip of Satan, for, as it is written, Jesus became blood and flesh “that through his death he might bring to nothing the one having the means to cause death, that is, the Devil; and that he might emancipate all those who for fear of death were subject to slavery all through their lives.”​—Heb 2:14, 15.

Continues to fight Christians. After Jesus’ death and resurrection, Satan continued to wage a bitter fight against Christ’s followers. The accounts in the book of Acts and in the letters of the Christian Greek Scriptures furnish numerous proofs of this. Paul said that he had been given “a thorn in the flesh, an angel of Satan, to keep slapping” him. (2Co 12:7) And as in the case with Eve, Satan disguised his real nature and purposes by “transforming himself into an angel of light,” and he had agents, ministers who “also keep transforming themselves into ministers of righteousness.” (2Co 11:14, 15) Examples of these were the false apostles who fought against Paul (2Co 11:13) and those in Smyrna ‘who said they themselves were Jews, and yet they were not but were a synagogue of Satan.’ (Re 2:9) Satan never ceased in making accusations “day and night” against Christians, challenging their integrity, as he did Job’s. (Re 12:10; Lu 22:31) But Christians have “a helper with the Father, Jesus Christ, a righteous one,” who appears before the person of God in their behalf.​—1Jo 2:1.
