The spirit of adoption (pneuma huiothesias). See note on this term huiothesia, on Gal 4:4. Also see Gal 4:5. Both Jews and Gentiles receive this “adoption” into the family of God with all its privileges. “
Whereby we cry, Abba, Father” (en hēi krazomen Abbā ho patēr). See note on Gal 4:6 for discussion of this double use of Father as the child’s privilege.
