I have hidden your word in my heart that I might not sin against you. Psalm 119:11
We most likely wouldn't hide something of little or no value. We would only make the effort if it was something of great worth. I would think that our expectation would be to hide it for some future purpose.
That's why we should commit ourselves to studying God's Word. It's not so we can impress anyone with our knowledge and ability to recall long passages. We do this so that the power of the right path is there when we need it.
