Romans 8:16-18 The Spirit Himself bears witness with our spirit that we are children of God.

CAB⁽ⁱ⁾ ¹⁶ The Spirit Himself bears witness with our spirit that we are children of God. ¹⁷ And if children, then heirs--heirs of God and joint heirs with Christ, if indeed we suffer together, so that we may also be glorified together. ¹⁸ For I consider that the sufferings of this present time are not worthy to be compared with the coming glory to be revealed in us.
