We, those called by God to be saved by His Grace, are adopted into His family receiving all the rights as true heirs:

For all who are being led by the Spriti of God, these are sons of God.  For you have not received a spirit of slavery leading to fear again, buty you have received a spirit of adoption as sons by which we cry out < "Abba! Father!"  The Spirit Himself testifies with our spirit that we are children of God and if children, heirs also, heirs of God and fellow heirs with Christ, if indeed we suffer with Him so that we may also be glorified with Him.
 Rom. 8:14-17
