n°45 / The Epistle to the Romans 8 :

24For we are saved by hope : but hope that is seen is not hope : for what a man seeth, why doth he yet hope for ?
25But if we hope for that we see not, then do we with patience wait for it.
26Likewise the Spirit also helpeth our infirmities : for we know not what we should pray for as we ought : but the Spirit itself maketh intercession for us with groanings which cannot be uttered.
