It’s that “all” that makes it “is” rather than “are,” because the “all” there represents the singular totality of the “glory and honor.” I’d try to explain better but I’m on my way out the door!
I am grateful for the comments and opinions various writers have made. I think Fieldsparrow’s point (albeit made in haste) is probably best (again, I emphasise, from the grammatical, not theological, point of view. When the word “all” qualifies abstract, non-quanitfiable subjects, it usually takes a singular verb in English.
I have to disagree here - I don’t think “all” has anything to do with it (I’ll explain that in a bit).
Depending on how the sentence is set up, “all” can be an adjective or a subject.
Subject (modified by prepositional phrase): “All of my exes is in Texas.”
Adjective (modifying the subject): “All my exes is in Texas.”
Or you could argue that the “of” is assumed, and that it’s still a subject in the second example. It doesn’t really matter, singular is obviously wrong - “All” is clearly plural, reflecting the noun “exes.”
Robert Aston argues that rules are different for abstract, non-quantifiable nouns, so let’s use a compound phrase that fits that description.
“All my hope and fear has melted away”? No.
“All my hope and fear
have melted away.”
The compound subject makes it plural. If you’re not convinced, let’s expand our compound subject:
“All my hope and fear and itchiness and skill and derring-do and citizenship and contempt and intelligence has melted away.”
It’s obviously more appropriate to use the plural “have”.
It also doesn’t really matter whether the “all” is present or not.
seagal, however, has hit on a category where the singular would be appropriate, if the phrase is so conjoined that it is thought of as one, like bread and butter. The other examples I can think of like “peanut butter and jelly” all imply an unnamed singular noun, in this case sandwich. Getting back to the OP, one could argue that “glory and honor” is just such a conjoined phrase (my term) that it merits treatment as a singular. I would suggest a test is whether you could substitute “both” or “either” for “all”.
Yes, the glory and honor occur together, but unlike “bread and butter,” you can separate the two by adding adjectives to one and not the other, you can add a third noun to the list, etc, and so obviously you can also make a coherent sentence using “both” or “either” in place of “all”.
