Too much truth about a mile wide and an inch deep.
I do think though, that Christian weakness has more to do with
PRIDE, SELFISHNESS, FEAR
than a LOT of other things.
I simply choose music which edifies me, builds me up and draws me closer to God. A reasonable range does that and certainly The Blood and The Cross are recurring themes in my collections.
As I said before, the problem is that many (most?) churches are eliminating all but the fluff, and that, IMO, is dangerous.
Pride and selfishness are not far removed from the motivation to do only music which entertains us and makes us 'feel good.' I think they are interrelated with the shallowness of contemporary worship in what is contributing to the wimpiness of American Christianity.
