Romans 8:14-17

For all those led by God’s Spirit are God’s sons. For you did not receive a spirit of slavery to fall back into fear. Instead, you received the Spirit of adoption, by whom we cry out, “Abba , Father!” The Spirit himself testifies together with our spirit that we are God’s children, and if children, also heirs  — heirs of God and coheirs with Christ — if indeed we suffer with him so that we may also be glorified with him.
