Mt. 18:1-14; Mk. 9:33-50; Lk. 9:46-50
When people work closely together, some like Peter, James and John become closer to their leader. This sometimes causes a certain amount of envy and jealousy. That was likely the cause of a dispute on the way to the house in Capernaum. The apostles turned to Jesus for the answer. They asked, “Who then is greatest in the kingdom of heaven?”
He set a little child before them as an example of humility and stated that they must be converted and become as little children if they were to enter the kingdom of heaven. Those who would be first, must put themselves last by serving others first. Note: He did not say, “Come as little children,” but, “Become as little children.”
Jesus pointed out the importance of righteous living. Even the most trivial thing done for someone else in His name will not go unnoticed—even a cup of water. He stated that if a member of the body caused a person to sin, he would be better off without that member, than to be cast into the everlasting fire.
