Romans 8:13-16New International Version (NIV)

¹³ For if you live according to the flesh, you will die; but if by the Spirit you put to death the misdeeds of the body, you will live.

¹⁴ For those who are led by the Spirit of God are the children of God. ¹⁵ The Spirit you received does not make you slaves, so that you live in fear again; rather, the Spirit you received brought about your adoption to sonship.^[a] And by him we cry, “Abba,^[b] Father.” ¹⁶ The Spirit himself testifies with our spirit that we are God’s children.

Romans 8:26New International Version (NIV)

²⁶ In the same way, the Spirit helps us in our weakness. We do not know what we ought to pray for, but the Spirit himself intercedes for us through wordless groans.
