Evil spirits couldn't stand to be in the presence of the Messiah.
It was an integral part of his mission, as Matthew narrates in his Gospel, “That evening they brought to him many who were possessed with demons; and he cast out the spirits with a word, and healed all who were sick” (Matthew 8:16).
Among other things, it was a reminder to all that he was God and evil spirits can not stand to be in his presence. They disobeyed him once before and are forever repelled by his divine goodness.
Here are four episodes from the Gospels that relate this extraordinary power, reassuring us today that if we ever feel oppressed by evil, invoking Jesus’ intercession is the surest way to expel that darkness.
