'If we hope for what we do not yet have, we wait for it patiently.' (Romans 8:25)

As hope sustains those who are suffering, the Holy Spirit is able to help in prayer.

The relationship between the Holy Spirit and God is so close that the Holy Spirit's prayers do not need to be spoken in words, as God knows his every thought.

'He who searches our hears knows the mind of the spirit.' (Romans 8: 27)
