Romans 8:12-17

12Therefore, brethren, we are debtors, not to the flesh, to live according to the flesh. 13For if ye live according to the flesh, ye shall die: but if ye through the Spirit mortify the deeds of the body, ye shall live. 14For as many as are led by the Spirit of God, they are the sons of God. 15For ye have not received the spirit of bondage again to fear; but ye have received the Spirit of adoption, by which we cry, Abba, Father. 16The Spirit himself beareth witness with our spirit, that we are the children of God:

17And if children, then heirs; heirs of God, and joint-heirs with Christ; if so be that we suffer with him, that we may be glorified together.
