Romans 8:14-18

For all who are being led by the Spirit of God, these are sons and daughters of God.

For you have not received a spirit of slavery leading to fear again, but you have received a spirit of adoption as sons and daughters by which we cry out, “Abba! Father!”

The Spirit Himself testifies with our spirit that we are children of God,

and if children, heirs also, heirs of God and fellow heirs with Christ, if indeed we suffer with Him so that we may also be glorified with Him.

For I consider that the sufferings of this present time are not worthy to be compared with the glory that is to be revealed to us.
