"Do Christians have the authority to rebuke the devil?"
As Christians, we need to be aware of the reality of the presence of evil. As we struggle to stand firm in our faith, we must realize that the enemies we are up against are not merely human ideas, but real forces that come from the powers of darkness. The Bible says,
12For we wrestle not against flesh and blood, but against principalities, against powers, against the rulers of the darkness of this world, against spiritual wickedness in high places. (Ephesians 6:12)Clearly, God has allowed Satan significant amounts of power and influence over the earth, at least for the time being. The Bible tells us that he is prowls around like a lion in search of prey, looking for victims to devour (1 Peter 5:8). Satan is the power at work in the hearts of those who refuse to obey God (Ephesians 2:2). Anyone who is not under the control of the sovereign God is under the control of the Devil (Acts 26:18; 2 Corinthians 4:4). Born-again Christians are no longer enslaved to Satan, or to sin (Romans 6:6-7), but this does not mean we are immune to the temptations that he puts before us.
The Bible does not give Christians the authority to rebuke the Devil, but to resist him. James 4:7 tells us to "Submit yourselves therefore to God. Resist the devil, and he will flee from you." Zechariah 3:2 tells us that it is the Lord who rebukes Satan. Even Michael, one of the most powerful of the angels, did not dare to accuse Satan, but rather said, "The Lord rebuke you" (Jude 1:9). In response to Satan's attacks, a Christian should hide under the covering of Christ. Instead of focusing on defeating the Devil, we should focus on following Christ (Hebrews 12:2).
It is not necessary for a Christian to rebuke Satan because God has given us His full armor to stand against evil (Ephesians 6:10-18).
10Finally, my brethren, be strong in the Lord, and in the power of his might. The most effective weapons we have against the Devil are our faith, wisdom, and knowledge about God and His Word. Even Christ, when tempted by Satan, did not rebuke him but answered him with Scripture (see Matthew 4:1-11). To gain victory in spiritual matters, we must maintain a clear conscience and have control over our thoughts.
11Put on the whole armour of God, that ye may be able to stand against the wiles of the devil.
12For we wrestle not against flesh and blood, but against principalities, against powers, against the rulers of the darkness of this world, against spiritual wickedness in high places.
13Wherefore take unto you the whole armour of God, that ye may be able to withstand in the evil day, and having done all, to stand.
14Stand therefore, having your loins girt about with truth, and having on the breastplate of righteousness;
15And your feet shod with the preparation of the gospel of peace;
16Above all, taking the shield of faith, wherewith ye shall be able to quench all the fiery darts of the wicked.
17And take the helmet of salvation, and the sword of the Spirit, which is the word of God:
18Praying always with all prayer and supplication in the Spirit, and watching thereunto with all perseverance and supplication for all saints;
"For though we walk in the flesh, we do not war after the flesh:
(For the weapons of our warfare are not carnal, but mighty through God to the pulling down of strong holds;) Casting down imaginations, and every high thing that exalteth itself against the knowledge of God, and bringing into captivity every thought to the obedience of Christ" (2 Corinthians 10:3-5).
