John 1
12 Yet to all who received him, to those who believed in his name, he gave the right to become children of God 13 children born not of natural descent, nor of human decision or a husbands will, but born of God.
Jews who reject the Messiah are certainly not children of God in the sense indicated in this passage. They are His children of natural descent, but they are alienated from His spiritual family and eternal inheritance. So the sense of how you use the word children is important.
