God has made us His sons and daughters because of Jesus. Through adoption we have a sense of belonging, value, and being loved.

Westminster Confession on Adoption-
All those that are justified, God vouchsafes, 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.
