"equal sign idiom/icon" and Matthew 6:10

AMP Visual works with U2, and have a running series of blog posts  called U2 x5:

 U2 x 5, whereby we take 5 related pieces we’ve designed or been involved with for the band and comment on them, we thought we’d share some things we’ve done for U2 that through design or accident aren’t at first or even second look easily seen. Mostly these elements were obscure or hidden, sometimes deliberately so and sometimes we included them just for fun.

An intriguing mention below.  They mention sometimes getting direct input/ideas from the band; the classic example is photoshopping the Jeremiah 33:3 reference onto the cover on "All That You Can't Leave Behind."   So could it be that the Scripture  the AMP people mentioned below in connection with the "equal sign" cover of "No Line,"..a Scripture which many have seen as the interpretive key to the whole album (see this, this...and read some NT Wright in tandem with a spin of the album)  was mentioned by Bono  himself to the AMP people?  They got the text from someone official, I would assume.
I love that they call the equal sign an "idiom."  Isn't it also an icon?:

 No Line On The Horizon – album sleeve
One of the themes within the album is that of universal balance and contrast, of night and day. It’s from this theme that we came up with the equals mark idiom as a form of title for the album, from the universal language of mathematics. The implication is of parallel force; of harmony and discord as in Matthew 6:10 …on earth as it is in heaven. To further the mathematical theme, in the digipak version of the album we put in a little hidden code – a piece of the Fibonacci sequence. Named after an Italian mathematician, the number sequence is related to the golden section, an ideal natural ratio as seen in art and architecture and in abundance in natural structures. It’s a numerical sequence that is a beautiful example of natural balance and equilibrium.  AMP Visual , emphasis mine
