The first talk/article I'll share here is from Elder Joseph B. Wirthlin, and is the talk where you can find the quote from the above description of this blog. The article title is:
"One Step after Another" and can be found in the November 2001 Ensign (you can also click on the link to see the article).
I've chosen this article because Elder Wirthlin really captures how we can make it. He doesn't tell us we have to be perfect now ... or even tomorrow. But he does tell us to work hard, to keep trying, and we can make it. He tells us to keep reaching for eternity, for exaltation, one step at a time.
