Romans 8:25-27

But if we hope for that which we see not, then do we with patience wait for it. And in like manner the Spirit also helpeth our infirmity: for we know not how to pray as we ought; but the Spirit himself maketh intercession for us with groanings which cannot be uttered; and he that searcheth the hearts knoweth what is the mind of the Spirit, because he maketh intercession for the saints according to the will of God.
