Romans 8:24-27

24For we have been saved in hope; but hope seen is not hope; for what any one sees, why does he also hope?

25But if what we see not we hope, we expect in patience.

26And in like manner the Spirit joins also its help to our weakness; for we do not know what we should pray for as is fitting, but the Spirit itself makes intercession with groanings which cannot be uttered.

27But he who searches the hearts knows what [is] the mind of the Spirit, because he intercedes for saints according to 1God.
