Timothy Keller shows how good things become idols when they become ultimate things, when we look to them for our meaning. Throughout the book he uses biblical characters to illustrate how idols work in our lives to cause destruction. I felt that sometimes he pushed the explanations a little further than the biblical accounts warranted.

Keeping God front and centre in your life is always difficult and Keller is realistic in his assessment that in this life we will need to continually removing the idols that spring up in our hearts. While much of it was covering old ground, he offers some good questions to ask when examining yourself and gives his remedy to idols - don't love the good things (like family) less, love God more.
