People, even the disciples, struggled to get it, but the demons clearly knew who Christ was. They recognized Him every time. James 2:19 says they “believe” in Christ and “shudder” in His presence. The lovers of darkness hate the light. They were always agitated in Christ’s presence. They knew that their days were numbered. They knew that Jesus was (as the verses say) “the Holy One of God” and “the Son of God.” And though it was more out of fear than reverence, they knew Christ has a greater authority than they did.
