Romans 8:14 NASB For all who are being led by the Spirit of God, these are sons of God. Romans 8:15 NASB For you have not received a spirit of slavery leading to fear again, but you have received a spirit of adoption as sons by which we cry out, “Abba! Father!” Romans 8:16 NASB The Spirit Himself testifies with our spirit that we are children of God, Romans 8:17 NASB 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.
