Romans 8:14-17  (NIV)

¹⁴ For those who are led by the Spirit of God are the children of God. ¹⁵ The Spirityou received does not make you slaves, so that you live in fear again; rather, the Spirit you received brought about your adoption to sonship.^[a] And by him we cry, “Abba,^[b] Father.” ¹⁶ The Spirit himself testifies with our spirit that we are God’s children. ¹⁷ 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.
