The Spirit you received does not make you slaves, so that you live in fear again; rather, the Spirit you received brought about your adoption to sonship. And by him we cry, “Abba, Father.”
The Spirit himself testifies with our spirit that we are God’s children.
Now if we are children, then we are heirs—heirs of God and co-heirs with Christ, if indeed we share in his sufferings in order that we may also share in his glory.
I consider that our present sufferings are not worth comparing with the glory that will be revealed in us.
