Answer
Satan is Godâs great enemy, and therefore the enemy of Christians as well. Among several other names, Satan is known as the accuser.
Satan was formerly a beautiful and powerful cherub, likely the highest of all angels. But iniquity was found in him (Ezekiel 28:15), and he was lifted up in pride, desiring to be greater than the Lord God (Isaiah 14:12–15). He led an army of angels into rebellion, which resulted in his ejection from heaven—along with every angel who had followed him (Ezekiel 28:17–18). Now Satan prowls the earth, seeking to hinder all he can from choosing salvation and living a life of obedience (1 Peter 5:8). In addition, Satan acts as the accuser of believers in an attempt to discredit them before God.
For the time being, God has allowed Satan the accuser limited access to heaven. In the book of Job, we see Satan stand before God and accuse a righteous man named Job, claiming that Job is only faithful because God had blessed him abundantly (Job 1:9–10). Satan posits that, if Job is put to the test, he would eventually turn from God and forsake his righteous life (verse 11; 2:4–5). In His omniscience, God knows that Job will remain steadfast, and He gives Satan the accuser permission to test Job.
The book of Revelation tells us a bit more about Satanâs role as accuser: âThen I heard a loud voice in heaven say: âNow have come the salvation and the power and the kingdom of our God, and the authority of his Messiah. For the accuser of our brothers and sisters, who accuses them before our God day and night, has been hurled downââ (Revelation 12:10). Satan is relentless in his accusations—he accuses Godâs children continually. He hates God and all that God is, which means he also hates Godâs mercy and forgiveness extended to sinful humanity. Satan the accuser stands before God in an attempt to somehow lessen Godâs love or diminish Godâs mercy. Fortunately, his accusations against us fall on deaf ears: âWho will bring any charge against those whom God has chosen? It is God who justifiesâ (Romans 8:33). Salvation belongs to the Lord, and His justification cannot be reversed. God is greater than our accuser.
Satan the accuser desires to remind believers of their sin and their unworthiness of a place in Godâs family and in this way sow doubt into their hearts and minds. Satan wants to make Christians fear for their salvation and forget Godâs love and faithfulness. Satan says, âLook at your sinfulnessâ; God says, âLook to Jesus, the author and finisher of your faithâ (see Hebrews 12:2).
In spite of Satanâs accusations and deceptions, God will not change His mind about those He has called to salvation (Romans 8:38–39). He has set the accuserâs ultimate fate: âAnd the devil, who deceived them, was thrown into the lake of burning sulfur, where the beast and the false prophet had been thrown. They will be tormented day and night for ever and everâ (Revelation 20:10). After God creates the new heaven and new earth, Satan will be absent for eternity (Revelation 21:1–4, 27). Believers can rest in the knowledge that our salvation is sure (Romans 11:29; Ephesians 1:13–14) and take comfort in the promise that God will complete the good work He began in us (Philippians 1:6).
In his book The Pilgrimâs Progress, John Bunyan describes a battle between the accuser, Apollyon, and Christian in the Valley of Humiliation. One of Apollyonâs ploys is to recite a laundry list of Christianâs sins: âThou didst faint at first setting out, when thou wast almost choked in the Gulf of Despond; thou didst attempt wrong ways to be rid of thy burden, whereas thou shouldst have stayed till thy Prince had taken it off; thou didst sinfully sleep and lose thy choice thing; thou wast also almost persuaded to go back at the sight of the lions; and when thou talkest of thy journey, and of what thou hast heard and seen, thou art inwardly desirous of vain-glory in all that thou sayest or doest.â
Christianâs response to the accuser is full of humility and faith: âAll this is true; and much more which thou hast left out: but the Prince whom I serve and honour is merciful and ready to forgive. But besides, these infirmities possessed me in thy country; for there I sucked them in, and I have groaned under them, been sorry for them, and have obtained pardon of my Prince.â At the mention of Christâs forgiveness, Apollyon flies into a rage; Satan the accuser cannot abide the fact that his accusations are overcome by the grace of God in Christ.
