I have had the wonderful honor and joyful privilege to interview Dr. Andreas Köstenberger and his wife Dr. Margaret Köstenberger on my daily, live Christian broadcast, IronSharpensIronRadio.com, and I eagerly look forward to their return as my guests soon, and often! . . . Their brilliance and unwavering commitment to God-breathed truth is matched by their humility, cordiality, and irenic spirit.

Of the making of websites there is no end, including websites that have to do with the Bible, but Andreas Köstenberger has done something extremely valuable and somewhat unique. He is an expert in the Bible, not merely a pundit, and he is offering all kinds of resources on a host of related topics, including biblical theology, women, various books of the Bible, and numerous other things FOR FREE! . . . Skip other websites and bookmark this one! Highly recommended.
