Glad you like it, 5teve! I got pretty excited when I first researched it. Apparently, whole books of the Bible (and the Book of Mormon, I'm told) are organized in chiasmus. I haven't checked that personally, but it's a cool idea.
I notice in this example, you use chiasmus of meaning, but you have an extra line in there, seven in the first half, eight in the second. Visually, the long lines tapering to short then back again show the form.
