"The Spirit helps us in our weakness," Romans 8:28.
How weak are we? We don't have a clue about spiritual protocols in the presence of the Creator of all worlds. When we go to God in prayer, which he encourages us strongly to do, we don't know even what to say. We don't even know how to speak with the Majesty, the King of kings, the Lord of lords. (We hardly even understand who we're talking to.) But no worries! God's own Spirit, alive within us, helps us in our prayers. The Spirit steps in between us and God and expresses the unwordable, even inaudible language of our hearts. And the thanksgivings and the petitions and the requests and the praises come into God's hearing exactly right.
We meet with a brother or sister today praying in weakness for God's power. And together we give thanks that he hears us, really hears us, just fine.
