The Devil's phrase, 'We are all children of God' is a clever (white) lie and deceptive trick of confusion.
Yes, we are all creation made in the Image of God, our Heavenly Father Who looks down on us "children of disobedience" (i.e. sinners) but the plain biblical truth is ONLY BORN AGAIN believers in Christ are "Children of God".
Only people who have acknowledged (admitted) their guilt as sinners by putting their faith on Jesus Christ are saved from their sins and are "spiritually-born" into the Family of God.
