What Mark 9:38 means
Plain-English insight for readers
In this verse, John, one of Jesus' disciples, reports to Jesus that they encountered someone who was casting out demons in Jesus' name, but he was not part of their group. John expresses concern and mentions that they tried to stop this person because he was not one of them. This highlights a common human tendency to protect one's group and to be wary of outsiders, even when they are doing good. Jesus responds to this by emphasizing that anyone who performs miracles in His name is on their side, regardless of their affiliation. This teaches that the work of God can be done by anyone who believes in Him, and it encourages inclusivity and acceptance of those who may not fit into our specific circles. It challenges the disciples' understanding of who can serve God and reminds them that God's power is not limited to a select few.
How to apply Mark 9:38 to your life
This verse encourages us to recognize and support the good works of others, even if they are not part of our immediate community. It reminds us to be open-minded and to celebrate the diverse ways in which God can work through different people, fostering unity rather than division.
