Romans 8:24-26 New International Version (NIV)
24 For in this hope we were saved. But hope that is seen is no hope at all.Who hopes for what they already have? 25 But if we hope for what we do not yet have, we wait for it patiently.
26 In the same way, the Spirit helps us in our weakness. We do not know what we ought to pray for, but the Spirit himself intercedes for us through wordless groans.
