Read Mark 9:38-50 with your family. Jesus told the disciples that someone else teaching about Jesus and God is not a problem. Jesus came with a very big message, and it takes all of us sharing it to make the world a better place. Do not worry about mistakes or anything bad, just share Jesus’ good news.
Jesus showed the disciples how silly they were by using sarcasm and exaggeration. He challenged them to cut off their foot, or their hand, or pluck out their eye if they got in the way of others sharing Jesus’ message. The disciples were being ridiculous. We choose to follow Jesus with our whole body, our whole heart and our whole mind. That’s how God made us.
