Matthew 15:13, 14 Jesus told His disciples to leave the Pharisees along because the Pharisees were blind to God's truth. Anyone who listened to their teaching would risk spiritual blindness as well. Not all religious leaders clearly see God's truth. Make sure those you listen to and learn from are those with good spiritual eyesight - they teach and follow the principles of Scripture.
Matthew 15:16-20 We work hard to keep our outward appearance attractive, but what is in our hearts is even more important. The way we are deep down (where others can't see) matters much to God. What are you like inside? When people become Christians, God makes them different on the inside. He will continue the process of change inside them if they only ask. God wants us to seek healthy thoughts and motives, not just healthy food and exercise.
Matthew 15:22 This woman is called "Greek", a Syro-Phoenician by birth" in Mark's gospel (7:26), indicating that she was from the territory northwest of Galilee where the cities of Tyre and Sidon were located. Matthew calls her a "woman of Canaan", naming her ancient ancestors who were enemies of Israel. Matthew's Jewish audience would have immediately understood the significance of Jesus helping this woman.
Matthew 15:23 The disciples asked Jesus to get rid of the woman because she was bothering them with her nagging persistence. They showed no compassion for her or sensitivity to her needs. It is possible to become so occupied with spiritual matters that we miss real needs right around us. This is especially likely if we are prejudiced against needy people or if they cause us inconvenience. Instead of being bothered, be aware of the opportunities that surround you. Be open to the beauty of God's message for all people, and make an effort not to shut out those who are different from you.
