I'm not even sure what he is trying to get at here. Obviously if he is just trying to say that all of our actions are conducted in a moral universe then he simply choose the wrong words to make his point.
Unfortunately, I think he may be trying to say much more.
For example, his little comment about the Hebrew language not having a word for "spiritual" seems a bit misleading. The Apostle Paul uses the term spiritual constantly and therefor the word spiritual must be a legitimate Biblical term when used in its proper context.
I found this spoof about him on you tube its pretty funny. The actor in this video proves that a good speaker can make even ridiculous statements sound plausible.

Oh yes and here is another great video produced by his church, from his "sex god" tour, whatever that is.
