Christ might have something to say about that..."If you love Me, you will keep My commandments"
You are correct, this is what Christ tells us in the Bible. To be a commandment keeper brings you naught. To love Him, brings you into commandment keeping.
I think you know that Mormons keep commandments (or lie about it) in order to obtain a Temple Recommend, so that they can partake of oaths and covenants, and receive "endowments" in order to "earn" themselves a higher kingdom, an eternal family, and worlds of their own creation. What is it that they love? Who's glory are they interested in?
Nuff said.
