So, JBJ's seven sevens in the 49-book Bible (what could be called the Jubilee Matrix) could be considered.
The 8th witness is our response. As ERH says, 'Respondeo etsi mutabor'--that's either I must respond though I will be changed, or I will respond though I must be changed.
This fits in with your 4-fold witness, the Trinity and the Bride, perhaps?
I've responded with BookBricks and calendar, etc., though google sites cut off one layer in one part, the basic JBJ Jubilee Matrix.
This is the most important thing I will write here: We are very deficient in responding.
ERH, in 'Magna Carta Latina,' writes that every Latin verb form is built up from a shorter imperative stem. This fits in with his view that each revolution starts with an imperative (Chapter 5 of Gardner's 'Beyond Belief' gives a good summary, and I've summarized the summary somewhere in ChuckHartmanHistoryConductor.
JBJ's Law-Lyric-Evaluation-Fact-New Torah echoes some of this, and more, of course--it's JBJ, after all.
What I would tell your listeners is this: The Law is 'Respond!'. Be the Bride, complete. Man initiates, Woman completes.
Love in King Jesus,
