In Matthew 18:7-14, Jesus was teaching how to enter into heaven. Then He began to teach about those who caused people to be lead astray or offended. He is trying to get people to understand what they do wrong is their fault. Jesus talked about people who causes offenses. Then Jesus explained one of the reasons He came to earth. He said that He came to save that which was lost. The teaching is the parable of the one and ninety nine sheep. He said He would leave the ninety nine and search for the one lost sheep. When He found the one lost sheep, He would rejoice more than about the ninety nine that stayed. God wants to gather us home, but we have to decide what we are going to do. Jesus is our shepherd, but we must follow Him.
