A more sure word of Prophecy

Romans 8:14-18 KJV
For as many as are led by the Spirit of God, they are the sons of God. [15] 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. [16] The Spirit itself beareth witness with our spirit, that we are the children of God: [17] 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. [18] For I reckon that the sufferings of this present time are not worthy to be compared with the glory which shall be revealed in us.
