Jesus crosses into the country of the Gerasenes and confronts a man enslaved by a legion of demons, a man whom no human power could restrain or restore. With sovereign authority, Christ delivers him, restores him to his right mind, and sends him home to tell what the Lord has done for him and how He has shown him mercy. Mark 5:1–20 reveals Jesus Christ as the mighty and merciful Savior who enters places of ruin, overcomes the powers of darkness, restores ruined sinners by His grace, and sends the redeemed to bear witness to His mercy. This passage confronts us with four great realities: the ruin of man under sin and Satan, the absolute authority of Jesus Christ, the danger of preferring our idols to the presence of Christ, and the calling of every redeemed sinner to testify to the mercy of God. There is no sinner beyond Christ's reach, no bondage stronger than His saving power, and no legion too great for the Son of God.
