Waiting upon the Lord is a common theme in the Bible (in the older sense of wait from the King James and Geneva versions) and appears in Psalm 37 a number of times, in Isaiah 64, and, perhaps most famously, in Isaiah 40:31. This is a very important message, in fact, since those mortals who believe themselves capable of contributing to their salvation (or that of others) fail to fully comprehend God's mercy and kindness. It is more relevant to heavenly salvation than to earthly works since it is the heavenly works that are beyond our control.
At the same time, though, some people might do well to observe what earthly matters they cannot control, and Wally, although not the paragon of the responsible worker, is perhaps right to question the need to divert great energy into a project that, given his past experience at the company, is likely to fail or to be cancelled before it has a chance to do so.
(Apparently, nobody here listens to Fred Hammond or Donnie McClurkin.)

Yeah, it's not in the Bible, just as "Cleanliness is next to Godliness" and "God works in mysterious ways" and "God helps those who help themselves" is not in there either.

Best of all, there's some extra subtle weaseling going on here: this being a comic, each letter of every word in the speech bubbles is capitalized, meaning that just as with any word we hear spoken, we can't be sure whether it's supposed to be capitalized or not. Wally could be referring to any written work he might think to be a bible for slackers, and to Snorlong the short-lived and purely imaginary god of slackers for all we know.

@DiFan007 Wally didn't specify which bible he was quoting. Let's here it for the "Wally Bible" A must read for any slacker.
