What authority do Christians have over Satan?

TL;DR:

Since death and sin reign in this world and in us, we have no authority to battle Satan. However, Christ, who lives within believers, overcame sin and death and has the ultimate victory over Satan.

what does the bible say?

Christians do not have authority over Satan on their own, but Christ, who lives within believers, has ultimate authority over him. While Satan has power, it is incomparable to God's. Jesus demonstrated His power over Satan through His ministry, including casting out demons and healing the oppressed. Ultimately, Jesus’ victory over sin and death proved His authority over all things, and believers have Christ living in them, by which they have authority over Satan. However, the call is not to battle Satan but rather to resist him. Believers have authority to resist Satan’s temptations and live holy lives by the power of the Holy Spirit. Believers rely on God's Word and the armor of God to stand firm against sin, temptation, and Satan’s schemes. In the end, Satan will be defeated when Jesus casts him into the lake of fire, and believers can rest in the assurance that Jesus' authority protects them.

from the old testament

God is the Creator of all things and His power is limitless and perfect in its nature, just as He is (Genesis 1:1). Satan has strong power, but it is nothing in comparison with God's.
The first demonstration we see of Satan wielding his evil influence is in the garden of Eden when he convinced Eve to eat from the Tree of the Knowledge of Good and Evil (Genesis 3). Adam and Eve gave their authority to Satan (Genesis 3:6).
God cursed Satan and banished him (Genesis 3:14-15; Isaiah 14:12-15).
Only God can tell Satan what to do (Job 1:12; 2:6).
God has power over life and death (1 Samuel 2:6
), and He has total power over Satan.

from the new testament

Satan tempted Jesus while He was fasting in the wilderness, but he could not get Jesus to sin (Matthew 4:1-11).
Jesus cast out demons (Matthew 8:16; Mark 1:34; Luke 8:27-33), showing His power over evil and Satan.
Jesus healed a crippled woman who was under the power of an evil spirit from Satan (Luke 13:11-13). Even though Satan had great power over this woman for eighteen years, just one encounter with Jesus freed her.
Satan is referred to as "the ruler of this world," but when Jesus returns He will cast Satan out once and for all (John 12:31).
Jesus gives us renewed authority over sin (Romans 7:24-25).
We can have victory over Satan’s temptations (1 Corinthians 10:13).
We have authority over our own personal temptations (2 Corinthians 10:5).
We fight against spiritual enemies (Ephesians 6:12).
Satan flees as we draw closer to God (James 4:7).
In the end, Jesus will cast Satan into the lake of fire for eternity (Revelation 20:7-10).

implications for today

Satan's primary power is the power of influence that we give him in order to deceive us and keep us under the power of sin rather than under the power of God (2 Corinthians 11:3; 2 Thessalonians 2:8-12). In and of ourselves, we have no authority over Satan. This is why we see non-believers living under the power of Satan, unable to resist sin. However, when we believe in Jesus Christ, His power that lives within us fights on our behalf. We are able to say "no" to sin, live holy lives, and be protected by God. When Jesus was tempted by Satan, He responded by quoting the Word of God (Matthew 4:1-11). Jesus is our example, so we, too, can defeat the Devil by the power of the Word of God (Ephesians 6:17). In the end, because Jesus has all authority in heaven and Earth, we will have total victory over Satan (Romans 16:20).

When we believe in Jesus Christ (John 3:16; Ephesians 2:8-9), we are indwelled with the Holy Spirit, and this is how we have power over the Devil. Galatians 2:20

says, "I have been crucified with Christ. It is no longer I who live, but Christ who lives in me." The same God who created the universe lives within us. When we live in submission to God's Spirit, we have power over Satan, because the power of Christ operates in and through us. Satan cannot overcome believers in Christ, because Satan cannot defeat the Spirit of God that inhabits them.This does not mean Satan will not try to harm us. The Bible instructs us: "Be sober-minded; be watchful. Your adversary the devil prowls around like a roaring lion, seeking someone to devour" (1 Peter 5:8). Satan will attack and deceive; he will be seeking an inroad into our lives. This is why as Christians, we are to: "Put on the whole armor of God, that you may be able to stand against the schemes of the devil. For we do not wrestle against flesh and blood, but against the rulers, against the authorities, against the cosmic powers over this present darkness, against the spiritual forces of evil in the heavenly places" (Ephesians 6:11-12). As Christians, while we may still struggle with evil and the temptation to sin, Satan will flee when we resist him in Jesus' name (James 4:7; 1 John 4:4).
