Two nebulous phrases in our theological discourses:
1. Build Zion
2. Do your best
If it helps:
Gordon B. Hinckley's definition of the phrase "build Zion":
"We can improve, and when all is said and done that's what this is all about: improvement, changing our lives so that we can help people change their lives and be better. And let's build Zion on the earth. That's what it is all about."
(Tacoma Washington Regional Conference, 19 Aug 1995)
David Bednar's definition of the phrase "do your best":
"You honor your covenants and are pressing forward."
(Evening with a General Authority, 25 Feb 2020)
