Romanos 8

15 Not for you received a spirit of bondage back to fear, but you received a spirit of sonship, by which we cry: Abba, the Father.

16 Itself the spirit testifies together with the spirit of us, that we are children of God.

17 If and children, also heirs; heirs indeed of God, jointheirs and of an Anointed; if indeed we suffer with, so that also we may be glorified with.
