The Bible teaches that Satan is the evil one. He is the ruler of this present evil age. When Satan tempted Jesus to worship him, he offered Jesus the kingdoms of this world, which is this present evil age. The Bible describes Satan's work in people, "whose minds the god of this age has blinded, who do not believe" (2 Cor. 4:4). In Jesus our Lord believers have the victory over Satan's power of darkness.
Satan as the "the god of this age" blinds the minds of those who believe not the gospel of Christ (2 Cor. 4:4). Works of the devil are based upon spiritual darkness, which includes unbelief, temptation, sin and death. God's power unto salvation is our victory through faith in the righteousness and resurrection of Christ (Romans 1:16-17).
Jesus Christ was born into this world to destroy the works of spiritual darkness. He came to destroy the works of the evil one. "For this purpose the Son of God was manifested, that He might destroy the works of the devil" (1 John 3:8). Works of the evil one include temptation, sin and death.
Jesus Christ was born to die for our sins according to the Scripture (1 Cor. 15:1-4). Jesus destroyed the power of death when He was raised from the grave. Jesus defeated the evil one through His death, resurrection, and ascension (1 Cor. 15:20-21; Eph. 4:8; Heb. 2:14-15). The gospel is our victory over the evil one as believers in the Lord Jesus Christ (1 Cor. 15:54-56; Rev. 12:11-12).
