Jesus for Jews only?

Matthew 10:5-6(NKJV)

5These twelve Jesus sent out and commanded them, saying: “Do not go into the way of the Gentiles, and do not enter a city of the Samaritans. 

6But go rather to the lost sheep of the house of Israel. 

While at first this may seem exclusionary, we know that God made other provisions through Paul to reach the Gentiles.  That part makes sense to me.  Then I cam across this.

Matthew 15:22-28(NKJV)

22And behold, a woman of Canaan came from that region and cried out to Him, saying, “Have mercy on me, O Lord, Son of David! My daughter is severely demon-possessed.”

23But He answered her not a word. And His disciples came and urged Him, saying, “Send her away, for she cries out after us.”

24But He answered and said, “I was not sent except to the lost sheep of the house of Israel.”

25Then she came and worshiped Him, saying, “Lord, help me!”

26But He answered and said, “It is not good to take the children’s bread and throw it to the little dogs.”

27And she said, “Yes, Lord, yet even the little dogs eat the crumbs which fall from their masters’ table.”

28Then Jesus answered and said to her, “O woman, great is your faith! Let it be to you as you desire.” And her daughter was healed from that very hour.

What I find interesting here is that Jesus was flat out ignoring this woman.  That sure is a different picture than most people have of a loving Jesus isn't it?  When she kept asking he even rebuked her for asking for His help.  He called her a dog.

Think of that!  Jesus degrading this woman and calling her a dog just because she asked for His help.  And He still wasn’t going to help her; until she said something that got His attention. 

What was the final reason that Jesus helped her?  It was her faith that caused Him to act.  Now think of what Jesus did for that faith.  He overrode God's plan. 

Think about it.  What was Jesus' reason for acting this way?  Jesus says He "was not sent except to the lost sheep of the house of Israel" and she was from Canaan.  Now who sent Jesus?  God did.  So Jesus is telling us that God sent Jesus only for the Jews.  And despite Jesus knowing that God sent Him only for the Jews, He disobeyed God and helped that Canaanite woman anyway.

What are we to think of that?  The other thing I wonder from this story is does it mean that there were many other people who he purposely denied His help to because they didn't come up with a quick witty response to demonstrate their faith?  If so whatever happened to the whole mercy and love thing?

Questions that will take more study.
