Holiness, like soap, doesn’t do much good until applied! You can keep it in a box, philosophize about it, and debate its merits at length, without ever getting around to using it.
Soul cleansing is like taking a shower. If you skip a day, you’ll be the only one to notice. If you skip a week, your family will notice. If you skip a month, everybody will notice!
Using soap is, indeed, much better than merely discussing it.
