Quoting a truth is easier than living it out in real life. Putting truth on a plaque or poster is nice, but it doesn't change a person's life.

Memorization of Scripture is good for retention, but it won't produce transformation in a person's life on its own. What we know in our minds doesn't automatically bring change in our hearts or our self-will.

Truth doesn't bring transformation until it's transferred from thought into action, which requires an active, personal faith.
