The podcast did not offer everything that is in the book but briefly went over some of the important topics in the book.
One thing that really stands out from the podcast is the simple use of the question.
A lot of Christians are not sure what to say or what to talk about in order to bring a spiritual conversation, some Christians are just afraid...
but the use of questions is an amazing thing.
First it puts the burden of proof on the other person. Second it makes you look like a good guy, you care and are asking great questions and are letting them share thier prespective. Thirdly it is safe. They are relational. They encourage your relationship with others.
Questions can be leading. can be investigative, or can be curious. If your friend says they do not believe in God for instances...instead of being afraid and feeling like you have to prove God, simply ask "What do you mean by God?" or "How did you come to that conclusion?"
Let them do the explaining...then after they have shared you can be ready to offer your own expirience or opinions in a kind but evangelistic manner.
I plan on getting this book and posting more about this book on my blog eventually. But check out the book Tactics. And the podcasts at Apologetics.com
