I have yet to read this book, but it is recommended by Dr. Joel Beeke and Tim Challies. Here is the Amazon production description:
How may Christians better understand the dangers and opportunities offered by the Internet? This book resource, written by an expert in the field, explains and illustrates what the technologies are and guides readers to draw on biblical principles (such as self-control and accountability) to help them to apply these to the dangers at hand. It also encourages believers to make the best use of opportunities that arise from judicious use of the World Wide Web.
Today some two billion people around the world use the Internet. Almost 80% of North Americans are connected to the web. But even as we use it, few of us understand the dizzying array of its applications and implications. David Clark guides us through the complexities of the Internet with simple, clear explanations. Even better, he unveils the spiritual implications of the Internet, both positive and negative. Pastors, parents, and teachers will greatly appreciate this book, as will the everyday Christian who, like me, is struggling to keep up with the ever-expanding universe of cyber-space, desiring to use it to God’s glory and the welfare of our families and Christ’s church.
