If you use Rabbi Micha Berger's approach in his Sefer Widen your Tent, then you will have an answer.

If I can paraphrase it correctly (I doubt that I can):

Kedusha is dedication, specifically -- when referring to Hashem -- dedication to bestowing goodness.

So, to answer your question:

קְדֹשִׁים תִּהְיוּ - become people dedicated to bestowing goodness on others

כִּי קָדוֹשׁ אֲנִי - for I am dedicated to bestowing goodness on others (as this is the purpose for which I created the world)

Thus:

• Rever your parents; it makes them feel good to be appreciated and honored - especially after all the dedicated kindness they did for you as a kid.

Same for Arayot, which you refer to:

• Don't cheat on your wife; that's extremely unkind. That takes care of most Arayot, at some level.
