In the story Matthew shared of Jesus blessing a Gentile woman in the area north of Israel one day, he quoted Jesus as saying to her that her faith was great. He didn’t comment on the object of her faith. I suggest that it was aimed at His character and His love, and not at His power. Your faith can aim there too, and also be full of great faith when you are seeking His help.
When Jesus left there, He withdrew to the area of Tyre and Sidon. Just then a Canaanite woman from that region came and kept crying out, “Have mercy on me, Lord, Son of David! My daughter is cruelly tormented by a demon.”
Yet He did not say a word to her. So His disciples approached Him and urged Him, “Send her away because she cries out after us.”
He replied, “I was sent only to the lost sheep of the house of Israel.”
But she came, knelt before Him, and said, “Lord, help me!”
He answered, “It isn’t right to take the children’s bread and throw it to their dogs.”
“Yes, Lord,” she said, “yet even the dogs eat the crumbs that fall from their masters’ table!”
Then Jesus replied to her, “Woman, your faith is great. Let it be done for you as you want.” And from that moment her daughter was cured.
