John speaks up and asks Jesus about a man who was casting out demons in His name. The disciples had apparently confronted him and informed him he could not do the work they were doing. Since this man was casting out demons, he was probably a believer in Jesus Christ but not one of Jesus’ twelve. The disciples thought they were better than everyone else because of their close association with Jesus. Jesus answers John’s question by saying, “Do not forbid him, for no one who works a miracle in My name can soon afterward speak evil of Me. For he who is not against us is on our side” (9:39-40). Jesus declares that anyone who does a good work in His name is, in essence, doing the work to Christ and will receive reward in the kingdom (9:41). Jesus then warns anyone who would contribute to a person’s unbelief or their turning away from God. The disciples were not to discourage people, whether an exorcist or little child, in their work for Jesus Christ but rather encourage it (9:42).
Jesus ends this teaching session with a command for His followers to guard themselves from sin. The illustrations He uses are graphic but remind the believer of the importance of keeping sin out of their life at any cost. Following Christ meant forsaking earthly desires so that we may pursue holiness and walk in God’s ways. Anything that would distract from this pursuit must be removed (9:43-50). “It is better to be a disciple and to enter eternal life maimed, minus earthly possessions that have been renounced, than to be an unbeliever. An unbeliever retains his allegiance to this world, refuses eternal life with God on His terms, and so will be thrown into hell” (The Bible Knowledge Commentary by John F. Walvoord and Roy B Zuck, p. 147.)
Dear God, help me to be a servant to all and guard against sin in my life that I may be a devoted follower of Jesus Christ.
