For whom do we groan?

I propose that nothing in the text warrants reading τὸ γὰρ τί προσευξώμεθα καθὸ δεῖ οὐκ οἴδαμεν [We don’t know what we should pray] in Romans 8:26 as a reference to the prayers believers should make only on their own behalf. Instead, what believers ought to pray for in Romans 8:26 and what the Spirit intercedes for in Romans 8:27 is not only for the believers’ own good but is also for the good of the creation, which currently groans, hence Paul’s transition from creation to believers in Romans 8:22–23.—Conformed to the Image of His Son, 244 (emphasis original)
