Are All MUSLIMS, JEWS and CHRISTIANS Children of GOD?

Pope Francis said just a few days ago that Muslims and Jews are our brothers and sisters. That is not the first time that he said that. The question a TRUE born-again believer in CHRIST (MESSIAH) must ask is how could that possibly be? The Islamic Koran teaches that God does not even have a Son, and most of the Jews do NOT believe that Jesus is the Son of God or Messiah either. In fact they ultimately turned Jesus over to the secular authorities to have him crucified. So how can a TRUE Christian be linked to people who flat out REJECT Jesus Christ? . . .
