Romans 8:12-17
8:12 So then, brothers and sisters, we are debtors, not to the flesh, to live according to the flesh--

8:13 for if you live according to the flesh, you will die; but if by the Spirit you put to death the deeds of the body, you will live.

8:14 For all who are led by the Spirit of God are children of God.

8:15 For you did not receive a spirit of slavery to fall back into fear, but you have received a spirit of adoption. When we cry, "Abba! Father!"

8:16 it is that very Spirit bearing witness with our spirit that we are children of God,

8:17 and if children, then heirs, heirs of God and joint heirs with Christ--if, in fact, we suffer with him so that we may also be glorified with him.
