Romans 8:16-18

Amplified Bible

¹⁶ The Spirit Himself testifies and confirms together with our spirit [assuring us] that we [believers] are children of God. ¹⁷ And if [we are His] children, [then we are His] heirs also: heirs of God and fellow heirs with Christ [sharing His spiritual blessing and inheritance], if indeed we share in His suffering so that we may also share in His glory.^(A)

¹⁸ For I consider [from the standpoint of faith] that the sufferings of the present life are not worthy to be compared with the glory that is about to be revealed to us and in us!
