Why Does the Gracious LORD Ignore Our Plea?

When a Canaanite woman begged Jesus to help her (by removing the demon that was tormenting her daughter), it seems like Jesus ignored and insulted her. However, he was actually strengthening her faith and preparing her for future hardships through this encounter. Our faith enables us to cling to his promise and know that he isn't ignoring us; rather, he answers our pleas and cares for us according to what is best for us.
