Jesus, as the Bible says, had been sent to the Israel. The problem was that His own people (Israel) did not receive Him. Bit as many as received Him, those who believed in Him, He gave them power to become Children of God. That woman being regarded in this verse was not a Jew and than is why Jesus used the terms to show that initially He had come to the Jews bit they did nothing receive Him. You have received Jesus and now you are a child of God. Halleluiah.
