Hi Pastor Roger,
Thanks for the welcome to the forum.
Curious as to where you might base your decision that he leads an extravagant lifestyle? Is this from personal experience? From what someone has told you? Or the media?
Pastor Warren lives in the same home he purchased 25 years ago. He added a spa and a pool since he bought it. He has one vehicle he drives as a primary vehicle and his wife has a vehicle as well. To me as a resident of Orange County, this is not considered extravagant.
The church itself has many people who donate to help build his resources there at the church for the community. But this does not reflect his personal lifestyle. There are lots of television evangelists who do have many homes, live a lifestyle well above the norm and reap in the benefits of their flock. Rick Warren is not one of them. He pays his staff well (I used to be on staff), as well as the pastors that work for him. But I certainly wouldn't call it extravagant by any means, and certainly not by Orange County standards.
As for the "works" comment, I see your point. However, this post was about his book. If you want to get into what he believes and teaches each week, go onto the website of Saddleback Church and browse around. Listen to one of his messages online. Watch a Sunday service. He follows Biblical scripture, teaches it in daily life and is never afraid to talk about the real subjects that affect people on a daily basis. A lot of people feel he is "fake" and isn't "traditional." If you have sat in the front few rows of the church you will realize he certainly is not traditional, but this is his teaching style and how he has grown his church.
You can start another post and say "What does Rick Warren teach" or "What does Rick Warren say about the Bible" and see what people might say. As for this one, we focused on what people said about book sales and what his book is talking about, getting involved and having a purpose in life beyond sitting in a pew. The beauty of this is also that many people are not open to the Word, so by presenting it in a book about being involved and giving of yourself, it opens up a conversation to discuss your beliefs. I have done the purpose driven life and 40 days of purpose. I have gone on missions, locally and within the US and while doing your "purpose" based on his book, it opens up an opportunity for the Word of God to be presented based on what I was doing to help others. People asked why I was there helping (Hurricane Katrina) and why I would give my time freely. To me, to be able to SHOW how God has used me to be able to help others is a great way to talk about the gospel and what I believed. It works beautifully together.
Thanks again for the welcome and the good conversation.
