Romans 8:9-17  NAS

However, you are not in the flesh but in the Spirit, if indeed the Spirit of God dwells in you.  But if anyone does not have the Spirit of Christ, he does not belong to Him.  If Christ is in you, though the body is dead because of sin, yet the spirit is alive because of righteousness.  But if the Spirit of Him who raised Jesus from the dead dwells in you, He who raised Christ Jesus from the dead will also give life to your mortal bodies through His Spirit who dwells in you.

So then, brethren, we are under obligation, not to the flesh, to live according to the flesh -- for if you are living according to the flesh, you must die; but if by the Spirit you are putting to death the deeds of the body, you will live.  For all who are being led by the Spirit of God, these are sons of God.  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!"  The Spirit Himself testifies with our spirit that we are children of God, 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.
