Romans 8:15-18 AMPC
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.
[But what of that?] For I consider that the sufferings of this present time (this present life) are not worth being compared with the glory that is about to be revealed to us and in us and for us and conferred on us!
