When evening came, they brought to him many who were demon-possessed. He drove out the spirits with a word and healed all who were sick
Matthew 8:16 (CSB)
The day Jesus healed Peter’s mother-in-law was a Sabbath, the Jewish day of rest. The Sabbath ended at sundown, and that is most likely why people waited until evening to bring their sick friends and family to Jesus (Mark 1:21, 32).
Some of the people they brought were sick, and some were troubled by evil spirits, which the Bible calls demons. Demons are spiritual beings who serve Satan and work against God. Jesus did not need any special ritual to deal with them. He spoke one word, and they had to leave, and He healed everyone who was sick.
Psalm 107 says this about God: “He sent his word and healed them” (Psalm 107:20). Jesus does by His own word what the Bible says God does, because He is God the Son. So when evil frightens us, like something terrible in the news or a temptation that feels too strong, we ought to remember that Satan, the evil one, has to obey Jesus.
Jesus did more than send demons away one evening. He died on the cross and rose again to break the devil’s power over everyone who trusts Him, and He sets us free from the fear of death (Hebrews 2:14-15).
