Don't be intimidated by those who call a Biblical worldview intolerant, and don't be frustrated by those who use a Biblical worldview to bludgeon other belief systems. Instead, learn to develop meaningful friendships rooted in meaningful conversations. Stanley J. Ward's _Worldview How to Share Your Faith and Keep Your Friends_ first introduces readers to the worldview concept, providing a simple (but not simplistic) way for readers to understand a Biblical worldview. He then provides readers with a simple (but once again, not simplistic) method for engaging in worldview conversations, partly inspired by Stephen Covey's advice, "Seek first to understand, then to be understood."
Ok, I'm a bit biased since I wrote this, but I believe that (a) the book provides a great introduction to the Biblical Worldview concept, and (b) it challenges the sometimes antagonistic mindset that a Biblical Worldview is often accused of. And it does all this in about 50 pages - so it is a book you can finish quickly! Recommended for both high school/college students and adults.
