Romans 8:14-17

For all who are led by the Spirit of God are sons of God. For [the Spirit which] you have now received [is] not a spirit of slavery to put you once more in bondage to fear, but you have received the Spirit of adoption [the Spirit producing sonship] in [the bliss of] which we cry, Abba (Father)! Father! The Spirit Himself [thus] testifies together with our own spirit, [assuring us] that we are children of God. And if we are [His] children, then we are [His] heirs also: heirs of God and fellow heirs with Christ [sharing His inheritance with Him]; only we must share His suffering if we are to share His glory.
