The reason the Son of God appeared was to destroy the devil’s work.
For our struggle is not against flesh and blood, but against the rulers, against the authorities, against the powers of this dark world and against the spiritual forces of evil in the heavenly realms. – Since the children have flesh and blood, he too shared in their humanity so that by his death he might destroy him who holds the power of death – that is, the devil… – And having disarmed the powers and authorities, he made a public spectacle of them, triumphing over them by the cross. – 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. They overcame him by the blood of the Lamb and by the word of their testimony; they did not love their lives so much as to shrink from death.”
But thanks be to God! He gives us the victory through our Lord Jesus Christ.
