Let’s start this post with one of the really controversial (according to a lot of people) passages in the Bible:
21 Leaving that place, Jesus withdrew to the region of Tyre and Sidon. 22 A Canaanite woman from that vicinity came to him, crying out, “Lord, Son of David, have mercy on me! My daughter is demon-possessed and suffering terribly.”
23 Jesus did not answer a word. So his disciples came to him and urged him, “Send her away, for she keeps crying out after us.”
24 He answered, “I was sent only to the lost sheep of Israel.”
25 The woman came and knelt before him. “Lord, help me!” she said.
26 He replied, “It is not right to take the children’s bread and toss it to the dogs.”
27 “Yes it is, Lord,” she said. “Even the dogs eat the crumbs that fall from their master’s table.”
28 Then Jesus said to her, “Woman, you have great faith! Your request is granted.” And her daughter was healed at that moment.
