"For as many as are led by the Spirit of God,they are the sons of God.
For ye have not received the spirit of bondage again to fear;but ye have received the Spirit of adoption,whereby we cry,Abba,Father.
The Spirit itself beareth witness with our spirit,that we are the children of God:
And if children,then heirs;heirs of God,and joint-heirs with Christ;if so be that we suffer with him,that we may be also glorified together."
Romans 8:14-17
