John 14:16, 17
And I will ask the Father, and He will give you another Advocate to be with you forever— / the Spirit of truth. The world cannot receive Him, because it neither sees Him nor knows Him. But you do know Him, for He abides with you and will be in you.
Romans 8:4
so that the righteous standard of the law might be fulfilled in us, who do not walk according to the flesh but according to the Spirit.
