Mark 1:25-26
25....."Be quiet!" said Jesus sternly. "Come out of him!" 26......The evil spirit shook the man violently and came out of him with a shriek.
Jesus had power over the evil one and the vile power he seeks to wield.
He defeated him during the temptation in the wilderness. He defeated
him in every encounter during his life. Most gloriously, he defeated
him in the place of Satan's greatest power -- death. Jesus' victory
over Satan and death will be most gloriously realized when he comes
again in glory with victory for all of his disciples.
