John 8:47
He that is of God heareth God's words: ye therefore hear them not, because ye are not of God — Jesus applies the principle: those who belong to God hear God's words (ta rhēmata tou Theou). The authorities do not hear them, which proves they are 'not of God.' Again, spiritual parenthood is determined by receptivity to God's truth. Jesus's words are God's words; they are God's word incarnate. To reject them is to prove oneself outside God's family.
