How does this verse relate to Luke 9:50: “Anyone who is not against you is for you”? In the earlier passage, Jesus was talking about a person who was driving out demons in Jesus’ name. Those who fight evil, he was saying, are on the same side as one driving out demons in Jesus’ name. Here, by contrast, he was talking about the conflict between God and the devil. In this battle, if a person is not on God’s side, he or she is on Satan’s. There is no neutral ground. Because God has already won the battle, why be on the losing side? If you aren’t actively for Christ, you are against him.
“Anyone who isn’t with me opposes me, and anyone who isn’t working with me is actually working against me. (Luke 11:23 NLT)
