Satan is styled the accuser of the brethren (Rev. 12:10—compare Job 1:6; Zech. 3:1), as seeking to uphold his influence among men by bringing false charges against Christians.
What does the Bible say about Satan the accuser?
Satan the accuser stands before God in an attempt to somehow lessen God’s love or diminish God’s mercy. Fortunately, his accusations against us fall on deaf ears: “Who will bring any charge against those whom God has chosen? It is God who justifies” ( Romans 8:33 ). Psalm 46:10: “Be still, and know that I am God: I will be exalted among the heathen, I will be exalted in the earth.” Exodus 14:14: “The LORD shall fight for you, and ye shall hold your peace.”
It is a constant battle we THINK we have to fight daily. However, reading the above verses, it tells that we have power standing behind us—who carries all the power in heaven and on earth (this includes the waters) and he fights battles for us.
Now someone may say, “But didn’t Jesus say to Satan, ‘Get thee behind me Satan?'”
Matthew 16:23: “But he turned, and said unto Peter, Get thee behind me, Satan: thou art an offence unto me: for thou savourest not the things that be of God, but those that be of men.”
Yes; however, he was rebuking Satan in Peter. And also, when we say (with our own lips), “Satan, get thee behind me,” those words hold Power—and Satan will flee.
It is important that we know these things, and let these words abide in us, so we can use them freely.
