Satan is a magnificent, mighty being with innate powers far beyond those of any fleshly creature, and as far as anyone knows he lives forever. Yet he has only the power God created in him and may use it only as far as God permits. Job 1:6-12 shows that Satan can do nothing against any of God's children that God does not allow. God puts a protective wall around His people and commands Satan, "This far and no farther." The Devil is in reality a dupe in God's hands, for God uses him to prepare His people for the Kingdom. Revelation 20:1-3, 7 shows the same limit: an angel binds Satan for a thousand years, and he is released for a little while only because God's purpose requires it. The power given to Satan is meted out for what God wants accomplished. Because of the horrors on earth, it may seem that his power is unlimited, but it most assuredly is not. The enemies of the church are humans influenced by Satan and his demons, such as the religious and civil leaders who persecuted Christ and the apostles. But God's authority over them is complete. Pilate's power came from above (John 19:10-11), the king's heart is in God's hand (Proverbs 21:1), and all authorities are appointed by God (Romans 13:1-2). Christ, who is head of all principality and power, has already defeated the principalities and powers through the conversion of Christians. Therefore, "If God is for us, who can be against us?" No one can stand in the way of God's purpose for His people.

Satan has only the power God gives him, and nothing more. In Job 1 and 2, Satan can touch nothing belonging to Job, and then nothing of Job's body, except as God permits, and God sets the boundary, even commanding that Job's life be spared. So Satan can do nothing against any of God's children that God does not allow. God puts a protective wall around them and tells Satan, "This far, and no further." Satan is in reality a dupe in God's hand, and God is overseeing the preparation of His children for the Kingdom. Revelation 20 shows the same limit: when God chooses, He cuts off Satan's power, and an angel who may have less power than Satan binds him, seals him in the bottomless pit for a thousand years, and releases him only for a short season afterward. Satan must bow before God's power. The same sovereignty covers the human instruments he influences. Pilate's authority was given from above, the king's heart is in the Lord's hand like channeled water (Proverbs 21:1), and no governing authority exists except by God's appointment (Romans 13:1). Christ has also defeated the demons, whatever their rank under Satan, having spoiled principalities and powers and triumphed over them (Colossians 2:15). He holds all authority, given by the Father, and is head of every principality and power. No enemy can deflect or nullify the unseen Power standing above all visible powers, so God's will stands.

Satan's power is strictly limited by God, who remains sovereign over all creation and ages. While satan may deceive, distort, and twist truth to serve his own agenda, he is not granted the authority to blind or open eyes, nor is he depicted as the God of any age. Scripture shows that he must seek permission from God to act, as seen in the cases of afflicting Job and sifting Peter. Though he may be inadvertently worshiped by some, his influence is confined within the boundaries set by God's will. God, in His supreme authority, controls the revealing and concealing of truth, blinding or opening eyes according to His purpose, while satan's role is limited to deception and encouraging human nature to suppress the truth that God has made available.

Satan acts only within limits God sets. In Job 1:6-12, Satan comes among the sons of God to present himself before the Lord, and it is God who takes the initiative, singling out Job, choosing the antagonist, and defining the boundaries of what Satan may do. God hands Job's possessions into Satan's power but forbids him to lay a hand on Job's person. Satan therefore cannot act apart from God's permission and direction, and God is actively directing him to carry out the trials God designs. God is the Prime Mover who creates calamity as well as peace, so no one can force anything upon Him, and even the greatest troubles come under His control. Trials that He arranges and oversees always serve one purpose: to produce righteousness and glorify God. Because God is in control, the one burdened can always overcome the trial, as I Corinthians 10:13 says. Job held his faith through the ordeal and God was pleased with him. This gives hope and encouragement, for Satan's attacks never escape the hand of the God who works all things together for good to those who love Him (Romans 8:28).

Christianity is not dualistic. God and Satan are not equal and opposing forces locked in an eternal struggle that ends in a tie. God is Sovereign over His creation, and that includes the subordinate domain of Satan; otherwise God is not sovereign at all, and if the dualists were right, everyone would be lost. Because good and evil are not equal powers, good always triumphs, and believers are not condemned to live eternally in chaos, subject to the fickleness of chance. God is the Lord of pain, disease, and death as well as life, blessing, and prosperity. He creates both light and darkness, peace and calamity (Isaiah 45:7). Job's trial shows that God can put anyone through any circumstance, and no purpose of His can be withheld. Job recognized that both good and evil are received from God's hand, and he came to see his suffering as part of God's creative activity. Jesus Christ continually upholds and sustains all things (Hebrews 1:3, Colossians 1:17), so God is never a distant clockmaker. All things, including suffering, work together for good for those who love God and are called according to His purpose (Romans 8:28), and nothing can separate them from Christ's love. God also never allows a test beyond what His people can bear (I Corinthians 10:13). Suffering is therefore a means of conforming them to the image of Christ, and it is a blessing rather than a curse.

Satan, once the perfect anointed cherub Helel, led a third of the angels in rebellion and was cast to earth, where he and his demons are now held in a place of restraint, a prison or "silo" (II Peter 2:4; Jude 6; Revelation 12). As a result, much of their former freedom and free moral agency was taken away. They are formidable, invisible, and numerous, as Daniel 10 shows when a demonic "prince of Persia" withstood an angel for three weeks until Michael helped. Yet several factors limit them. Good angels outnumber demons at least two to one and minister to the heirs of salvation, often unnoticed. The demons are a kingdom divided against itself (Matthew 12), held in line only by Satan's force. They also know God exists and tremble before Him (James 2:19). Most decisively, Job 1 and 2 show that Satan can do only what God permits: "He is in your hand, only do not lay a hand on his person." God sets limits on what Satan can do to each believer according to the measure of faith, love, and Spirit, and never gives a test greater than can be endured. Believers must still put on the whole armor of God (Ephesians 6) and hold their position, since the real enemies are spiritual powers. Victory is assured because Christ, who lives in them, has already defeated Satan.

Satan's power, though real and at times fearsome, is consistently portrayed as strictly bounded by God's sovereign authority, fitting within the larger demonstration that God rules over every category of His creation—inanimate, animate, angelic, and human. This principle emerges most clearly in the account of Eden, where Helel had to stand silently and receive his sentence without protest, and in the book of Job, where he could not touch Job until God granted permission, and even then could not cross the boundary line God had fixed, unable to kill him. Similarly, when Jesus confronted him directly in the wilderness temptation, a simple command—"Get you hence!"—was sufficient to make him depart; he had no power to resist that word. His ultimate end is also fixed by God's decree: he is destined to be cast into the lake of fire, confirming that his entire existence, from rebellion to final judgment, operates within limits God alone establishes. This limitation on Satan's power is set within a broader pattern of God's use of both good and evil spirit beings to accomplish His purposes. Just as God commands angels to perform functions in His governance of the earth—such as the single angel who destroyed seventy thousand Israelites at God's command and then was stopped the instant God said "It is enough"—He likewise directs evil spirits to fulfill His will. God sent an evil spirit to stir treachery between Abimelech and the men of Shechem to bring vengeance for Gideon's murdered sons, and in the case of Ahab, God took counsel with the host of heaven, allowing a lying spirit to volunteer to deceive Ahab's prophets and draw him to his death at Ramoth-gilead, while preserving the righteous Jehoshaphat. These examples reveal that evil spirits, including their chief, function as instruments subject to divine permission and command, never operating outside the sovereign will of God. This truth connects directly to the overarching message concerning God's meticulous oversight of His entire creation. Just as God governs weather, animals, kings, and even unconverted nations to accomplish His spiritual purpose, so too does He restrain and direct the power of Satan and demonic forces. Nothing—not natural law, not human rebellion, not the malice of evil spirits—operates independently of God's rule. This assurance grounds the peace available to the faithful: because Satan's power is never beyond God's control, believers can trust, as Jesus did while asleep in the storm-tossed boat, that their lives remain safely in the Father's hand regardless of apparent chaos or affliction.
