"Holy One" - Day 19 Mark 1:24-27 “What do you want with us, Jesus of Nazareth? Have you come to destroy us? I know who you are—the HOLY ONE of God!” “Be quiet!” said Jesus sternly. “Come out of him!” The impure spirit shook the man violently and came out of him with a shriek. The people were all so amazed that they asked each other, “What is this? A new teaching—and with authority! He even gives orders to impure spirits and they obey him.”
The demons recognize that Jesus, is holy, whole (wholly God), set apart from all others. A mere man cannot rebuke evil spirits without God's help. And even today, we can only overcome sin and all kinds of evil because of the power that Jesus gave to us when he died. Let's give thanks that Jesus, the Holy One, the only one who could save us, did come and provided a path back to righteousness!
