Likewise the Spirit also helps in our weaknesses. For we do not know what we should pray for as we ought, but the Spirit Himself makes intercession for us with groanings which cannot be uttered. Now He who searches the hearts knows what the mind of the Spirit is, because He makes intercession for the saints according to the will of God.
And we know that all things work together for good to those who love God, to those who are the called according to His purpose. —Romans 8:26-28 NKJV
