(a) Romans 8:17 heirs of God, and joint heirs with Christ

"To open their eyes, [and] to turn [them] from darkness to light, and  [from]  the power of Satan unto God, that they  may  receive forgiveness of sins, and inheritance among them which are sanctified by faith that is in me." (Acts 26:18)
"Wherefore  thou art no more a servant, but a son; and if a  son, then an heir of God through Christ." (Galatians 4:7)
