Apostol § 97

Brethren, as many as are led by the Spirit of God, these are sons of God For you did not receive the spirit of bondage again to fear, but you received the Spirit of adoption whereby we cry, "Abba, Father." The Spirit Himself bears witness with our spirit that we are children of God, and if children, then heirs; heirs of God and joint heirs with Christ, if indeed we suffer with Him, that we may be also glorified together. For I consider that the sufferings of this present time are not worthy to be compared with the glory which shall be revealed in us. For the earnest expectation of the creature eagerly waits for the manifestation of the sons of God. For the creature was mad subject to vanity, not willingly, but because of Him who subjected it in hope; because the creature itself also shall be delivered from the bondage of corruption into the glorious liberty of the children of God.
