'Sonship' in the Bible

For you have not received a spirit of slavery leading again to fear [of God’s judgment], but you have received the Spirit of adoption as sons [the Spirit producing sonship] by which we [joyfully] cry, “Abba! Father!”

For [even the whole] creation [all nature] waits eagerly for the children of God to be revealed.

that he might redeem those under law, that we might receive sonship.

For to which of the angels did the Father ever say,“You are My Son,Today I have begotten (fathered) You [established You as a Son, with kingly dignity]”?And again [did He ever say to the angels],“I shall be a Father to HimAnd He shall be a Son to Me”?
