Recommendation: re-read Romans 7-8 out loud.
What I’m suggesting is not a replacement for studying the Scriptures, nor for any other method of reading, but an alternative I’m suggesting can bear fruit from time to time.
On this occasion, read not with an eye to understanding what on earth Paul is trying to say in Ch 7, but with an eye to what happens to Paul as he contemplates God in the process of explaining to the believers in Rome.
By the time Paul gets to the end of Ch 8 he is enraptured by the character of God: caught up in delight at the recognition of the profundity of Who God is and what He does.
By the time he gets to 8:31 the quill of his amanuensis has begun to sing, the scratches on parchment become rhythmic, and in my mind’s eye, by the end of the chapter Paul is standing, arms trembling, voice crescendoing, and then he collapses to his knees as his spirit and the Spirit commune in adoration, before he has calmed and can resume penning what would become known as chapter 9.
All true theology is doxological.
