12So then, brothers and sisters, we have an obligation, but it isn’t an obligation to ourselves to live our lives on the basis of selfishness. 13If you live on the basis of selfishness, you are going to die. But if by the Spirit you put to death the actions of the body, you will live. 14All who are led by God’s Spirit are God’s sons and daughters. 15You didn’t receive a spirit of slavery to lead you back again into fear, but you received a Spirit that shows you are adopted as his children. With this Spirit, we cry, "Abba, Father." 16The same Spirit agrees with our spirit, that we are God’s children. 17But if we are children, we are also heirs. We are God’s heirs and fellow heirs with Christ, if we really suffer with him so that we can also be glorified with him.
