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.
The sense is that of any of the peoples who look to God and say "Abba." We can all have our peculiar doctrines that mutually exclude each other from the true "title" of child of God, or elect, or saved, or Catholic or whatever.
The point is, do we work from the assumptions brought to the table that those who reard God as father are trying to be His children? Or do we work from the assumption that everyone who isn't "with me" is an enemy, worthy of no respect whatsoever.

You are the sons of YHWH your God (Deuteronomy 14:1)
Behold, God is my salvation;
I will trust, and will not be afraid;
for God YHWH is my strength and my song,
and he has become my salvation. (Isaiah 12:2)
But Israel is saved by YHWH
with everlasting salvation (Isaiah 45:17)
