Idolatry in a Postmodern Age

I found this article by Tim Keller very helpful and was able to use the concepts here as a meditation to prepare my people for a sermon from Jeremiah in which the people of Israel are condemned for, among other things, idolatry. We spent a moment considering the first commandment and I quoted some of the comments from Martin Luther in order to help everyone recognize that we all are guilty of idolatry and, thus, this passage speaks to each of us. http://www.monergism.com/postmodernidols.html
