Evil spirits can’t rest in the presence of Christ.
Just then a man in their synagogue who was possessed by an impure spirit cried out, “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!”
Mark 1: 23-25
This story describes a guy sitting in the synagogue, looking like any other devout religious man of the time. (You must recognize that those being controlled by any type of evil spirit can look just as normal as you do. They may even appear to worship God.)
But this man is different and Jesus knows it. Jesus is not surprised by evil. You shouldn’t be either. Jesus comes in and the impure, evil spirit made it’s presence known publicly. The evil spirit recognizes Jesus. It knows that Jesus has the power to destroy it and the man he possesses. Jesus doesn’t answer his questions but commands him to come out.
Why didn’t the impure spirit keep quiet? Why did it make itself known? Because evil is restless in the presence of Jesus. It has to go. When Jesus is inside of you, some will reject you. They can not be around you. Their spirit can not rest when your spirit is around. Jesus is too powerful. Greater is he who is in you than he who is in the world. (1 John 4:4)
Jesus protects you. So when someone who is not walking with God gets taken out of your life, don’t fight God about it. It will be for your good.
