The Doctrine Of Adoption 1

All those that are justified, God vouchsafeth, in and for
his only Son Jesus Christ, to make partakers of the grace of
adoption, by which they are taken into the number, and enjoy
the liberties and privileges of the children of God, have his name
put upon them, receive the Spirit of adoption, have access to
the throne of grace with boldness, are enabled to cry, Abba,
Father, are pitied, protected, provided for, and chastened by him,
as by a father: yet never cast off, but sealed to the day of
redemption; and inherit the promises, as heirs of everlasting salvation. WCF
