Greatness in the Kingdom of Heaven

As the disciples argue about which of them is the best, they ask Him who is the greatest in the kingdom of heaven. He answers by directing their attention to a child and speaks at length of a child as the standard for entering the kingdom of heaven, how precious children and young believers are to the Lord, and the necessity of avoiding any occasion of causing them to sin. He also answers Peter's question about how many times he should forgive someone by telling the parable of the unforgiving servant.
