The Power of Humility

A woman desperate for the healing of her daughter.  Jesus calls her a dog in refusal!  How would you respond if you were the mother?  Would you be offended?  Wouldn't we all?  We labor so hard and so long to build up our self-esteem, but is that right?  Is it wasted time or is it even more dangerous than that?  Jesus seems not only unconcerned about our egos, but He seems to be set against them.  Does He have a point?  From Matthew 15:21-39.
