Q. Can you please explain why Satan is called the accuser? Who are the accused? What is he accusing about and does he still have that privilege to accuse anyone when he was already expelled from heaven?
A. The great dragon was hurled down—that ancient serpent called the devil, or Satan, who leads the whole world astray. He was hurled to the earth, and his angels with him. Then I heard a loud voice in heaven say: “Now have come the salvation and the power and the kingdom of our God, and the authority of his Christ. For the accuser of our brothers, who accuses them before our God day and night, has been hurled down.” (Rev. 12:9-10)
John heard a voice in Heaven saying that Satan is our accuser. According to this verse, the people he accuses are the believers, making sure God is always aware of our sins. Unfortunately, he won’t be cast out of Heaven until just before the beginning of the Great Tribulation.
But don’t worry. The Lord is right there to defend us every time we’re accused. In Romans 8:33-34 Paul wrote:
Who will bring any charge against those whom God has chosen? It is God who justifies. Who is he that condemns? Christ Jesus, who died—more than that, who was raised to life—is at the right hand of God and is also interceding for us.
