Clean heart

Matthew 15:1-39
Pharisees and teachers of the law care the clean and unclean hand to eat. But Jesus care the clean and unclean of heart.
What goes into the man's mouth does not make him 'unclean', but what comes out of his mouth, that is what makes him 'unclean.'"
These people honor me with their lips, but their heart are far from me. They worship me in van; their teachings are but rules taught by men.
Leave them; this is the way that Jesus told his disciple how to treat the Pharisees and teachers of law.
The faith of the Canaanite woman so great that her daughter was healed by Jesus from that moment.
Why?
Dog is the position of foreigner in Israel.
This woman accepted the test of Jesus for the faith, she believe only Jesus can heal her daughter, Jesus came for the salvation of Jews, but the gentile could be saved either.
Jesus have compassion for these people so Jesus give them to eat, there were about 4000 people, besides women and children.
From the first, Jesus teaching on religion brought him into conflict with the Pharisees. For them 'tradition was blinding.
But Jesus never hesitated to denounce tradition wherever it watered down or undermined scriptural principles. The ruling on vows is a case in point. People were allowed exemption from their duty to maintain their parents if they dedicated the money to God. That way they could still enjoy the proceeds.
It is not simply 'clean hands' but a 'clean heart' that matters.
The case of the centurion's servant makes it clear that race is not a barrier: God's kingdom is inclusive. So the harsh response would seem to be a test of faith.
Quick as a flash, the woman quips back. And Jesus will not refuse a request made with such tenacious faith.
How?
Keep me having a clean heart, please give me a clean heart and righteous soul to follow Jesus. Teach me the way to walk, Dear Lord.
