I came across this talk from Elder Henry B. Eyring explaining a little about the mechanics of learning line-upon-line, precept upon precept that I had never heard before. It helped me to understand a little better about how I can receive the next "line", and what to do if I get stuck.
"A Life Founded In Light And Truth", Elder Henry B. Eyring, BYU Devotional, 15 Aug 2000.
Obedience to commandments is the way we build a foundation of truth. Here is the way that works, in words so simple that a child could understand: The truth of most worth is to know God our Heavenly Father, His Son Jesus Christ, and Their plan for us to have eternal life with Them in families. When God communicates that priceless truth to us, He does it by the Spirit of Truth. We have to ask for it in prayer. Then He sends us a small part of that truth by the Spirit. It comes to our hearts and minds. It feels good, like the light from the sun shining through the clouds on a dark day. He sends truth line upon line, like the lines on the page of a book. Each time a line of truth comes to us, we get to choose what we will do about it. If we try hard to do what that truth requires of us, God will send more light and more truth. It will go on, line after line, as long as we choose to obey the truth. That is why the Savior said that the man who obeyed His commandments built on a rock so solid that no storm or flood could hurt his house.Did you catch that part that not a lot of people seem to understand?
