One of Satan's most painful activities is accusation. The book of Revelation gives him a formal title: "the accuser of our brethren, which accused them before our God day and night" Revelation 12:10. Think about that phrase. He accuses day and night. He does not take vacations. He does not sleep. He stands before God and argues against the people of God.

The Greek word for devil, diabolos, means slanderer or false accuser. Satan's very name describes his work. He slanders God to men, as he did in Eden when he said, "Hath God said...?" He slanders men to God, as he did when he claimed Job served God only for profit Job 1:9-11. His accusations often contain facts — you did fail, you did sin, you did doubt — but his conclusion is always a lie. The fact becomes a weapon, and the weapon is aimed at your identity.

The believer under attack must understand this office. Satan is not a vague feeling of guilt. He is a real prosecuting attorney who knows how to use the law against you. But he has a problem. The case against you has already been answered by the blood of Jesus and the advocacy of Christ.

The prophet Zechariah saw a courtroom scene that every believer needs to understand. Joshua the high priest stood before the angel of the Lord, and Satan stood at his right hand to resist him Zechariah 3:1. Joshua was clothed with filthy garments. The filth represented the sins of the nation and his own unworthiness. Satan's argument was obvious: this man is defiled. He cannot serve as priest.

Then the Lord rebuked Satan. "The Lord that hath chosen Jerusalem rebuke thee: is not this a brand plucked out of the fire?" Zechariah 3:2. The Lord ordered the filthy garments removed from Joshua and said, "Behold, I have caused thine iniquity to pass from thee, and I will clothe thee with change of raiment" Zechariah 3:4. Clean garments were put on him. A fair mitre was set upon his head.

This is a picture of every believer. Satan points to your past, your failures, your filthy garments. The Lord answers with redemption. The filthy garments are removed because of the cross. You are clothed with the righteousness of Christ. Satan's accusation is accurate about what you were, but it ignores what God has done.

Not every painful thought about sin comes from Satan. The Holy Spirit convicts. Satan accuses. These two sound similar, but they have opposite destinations.

Conviction from the Holy Spirit is specific, clean, and redemptive. He shows you a particular sin, calls you to repent, and points you to the mercy of God. Jesus said the Spirit would convict the world of sin, righteousness, and judgment John 16:8. Conviction hurts, but it does not crush. It leads to confession, forgiveness, and restoration. The voice of the Spirit says, "That was sin. Repent. You are still mine."

Accusation from Satan is vague, heavy, and hopeless. It does not point to one sin to be confessed. It points to your whole self as rotten. It says, "You always fail." "You are a hypocrite." "God is tired of you." "You were never really saved." Accusation leads not to repentance but to paralysis. It makes you hide from God instead of running to Him.

Paul described the difference in 2 Corinthians 7:10. "For godly sorrow worketh repentance to salvation not to be repented of: but the sorrow of the world worketh death." Godly sorrow produces life. Satanic sorrow produces death. If your sense of guilt makes you flee from God, it is not from God. If it makes you run to the cross, it is from the Spirit.

Accusation is one of Satan's most effective weapons because it stops believers from doing what God has called them to do. A person who feels disqualified will not step forward. A person who believes he is a failure will not try again. A person who is convinced that God is angry will not pray with confidence.

This paralysis affects every area of life. The young Christian who fell into sexual sin believes he can never be clean. The pastor who made a public mistake believes he can never preach again. The parent who failed a child believes the damage is beyond repair. The missionary who burned out believes God cannot use a broken vessel. In each case, the accusation has become louder than the gospel.

Satan's accusation also isolates. He wants you to believe that you are the only one who has failed this way. Shame thrives in secrecy. As long as your failure stays hidden, the accuser can keep speaking. James 5:16 gives the antidote: "Confess your faults one to another, and pray one for another, that ye may be healed." Confession to a trusted believer breaks the isolation and silences the accuser.
