“For though we walk in the flesh, we do not war according to the flesh. For the weapons of our warfare are not carnal but mighty in God for pulling down strongholds, casting down arguments and every high thing that exalts itself against the knowledge of God, bringing every thought into captivity to the obedience of Christ, and being ready to punish all disobedience when your obedience is fulfilled”. {2 Corinthians 10:3‭-‬6}.

Before ,you  participate  in  Spiritual  warfare , you must know , and believe  that,

“NO  WEAPON  FORMED  AGAINST  YOU  SHALL  PROPER, And every tongue which rises against you in judgment You shall condemn. This is the heritage of the servants of the Lord , And their righteousness is from Me,” Says the Lord .(Isaiah 54:17).

“Finally, my brethren, be strong in the Lord and in the power of His might. Put on the whole armor of God, that you may be able to stand against the wiles of the devil. For we do not wrestle against flesh and blood, but against principalities, against powers, against the rulers of the darkness of this age, against spiritual hosts of wickedness in the heavenly places.  Therefore take up the whole armor of God, that you may be able to withstand in the evil day, and having done all, to stand. Stand therefore, having girded your waist with truth, having put on the breastplate of righteousness, and having shod your feet with the preparation of the gospel of peace; above all, taking the shield of faith with which you will be able to quench all the fiery darts of the wicked one. And take the helmet of salvation, and the sword of the Spirit, which is the word of God; (“FOR  THE   WORD  OF  GOD  IS  QUICK, AND  POWERFUL, and sharper than any twoedged sword, piercing even to the dividing asunder of soul and spirit, and of the joints and marrow, and is a discerner of the thoughts and intents of the heart”. (Hebrews 4:12).  praying always with all prayer and supplication in the Spirit, being watchful to this end with all perseverance and supplication for all the saints— and for me, that utterance may be given to me, that I may open my mouth boldly to make known the mystery of the gospel, for which I am an ambassador in chains; that in it I may speak boldly, as I ought to speak. Peace to the brethren, and love with faith, from God the Father and the Lord Jesus Christ”. [Ephesians 6:10‭-‬20‭, ‬23].

Question: “Do Christians have the authority to rebuke the devil?”

Answer: There are some Christians who believe they not only have the authority to rebuke the devil, but also they must be about the business of rebuking him continually. There is no biblical basis for such a belief. Satan, unlike God, is not omnipresent. He can only be in one place at a time, and the likelihood of his personally harassing individual Christians is miniscule. Of course, he has legions of demons who do his bidding, and they are everywhere seeking to destroy believers’ testimonies. It should be noted here that the Christian cannot be possessed by a demon in the same way people in the Bible are described as being possessed.
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 our enemies are not merely human ideas, but real forces that come from the powers of darkness. The Bible says, “For our struggle is not against flesh and blood, but against the rulers, against the powers, against the world forces of this darkness, against the spiritual forces of wickedness in the heavenly places” (Ephesians 6:12).
Clearly, God has allowed Satan significant amounts of power and influence over the earth, at least for now, and always within God’s sovereign control. The Bible tells us that Satan 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 says to “submit yourselves, then, 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 appeal to Christ. Instead of focusing on defeating the devil, we should focus on following Christ (Hebrews 12:2) and trust that He will defeat the forces of evil.
It is not necessary for a Christian to rebuke Satan because God has given us His full armor to stand against evil (see Ephesians 6:10-18). The most effective weapons we have against the devil are our faith, wisdom, and knowledge about God and His Word. Christ, when tempted by Satan, 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. “For though we live in the world, we do not wage war as the world does. The weapons we fight with are not the weapons of the world. On the contrary, they have divine power to demolish strongholds. We demolish arguments and every pretension that sets itself up against the knowledge of God, and we take captive every thought to make it obedient to Christ” (2 Corinthians 10:3-5).
