Today, Warren Smith talks with George Barna, Joni Eareckson Tada, and Lauren Green. George Barna may be the most quoted and misquoted pollster in all of Christendom. He specializes in polling related to evangelicals, and a decade ago he set out to understand how many Americans, and how many born-again Christians, have a truly biblical worldview. Lauren Green currently serves as the chief religion correspondent for Fox News. She has covered virtually every major religion news story of the past two decades. Joni Eareckson Tada has become one of the truly inspirational leaders of the evangelical church. A diving accident when she was 17 has left her wheelchair bound for the past half-century, but ' with her likewise inspirational husband Ken Tada by her side ' she has built a large and effective ministry to the disabled.

Barnabas Piper was a regular contributor to the WORLD web-site for years and is also the son of the well-known pastor and occasional WORLD contributor John Piper. In fact, it was in his role as a 'PK,' or pastor's kid, that Barnabas Piper wrote his first book, "The Pastor's Kid: Finding Your Own Faith and Identity." Piper has gone on to have a robust writing and speaking career. His latest book is "The Curious Christian: How Discovering Wonder Enriches Every Part of Life." Piper lives and works for Lifeway Christian Resources in Nashville, Tennessee.

Ken Ham is the president of Answers in Genesis, an organization that operates the Creation Museum and the Ark Encounter, two well-known attractions in Kentucky. Ham is perhaps the country's best-known apologist for the idea that the universe is approximately 6,000 years old. In part because of his strong following in the fundamentalist and homeschool community, Ham has been the target of both favorable and unfavorable media attention. Ham has criticized other evangelical Christians who have a high view of biblical authority but who disagree with him on the belief that creation took place over six 24-hour days.

Johnson is the President and CEO of the National Religious Broadcasters (NRB), which is an international association of Christian communicators whose member organizations reach millions of viewers, listeners, and readers worldwide.

It is also in part Mindy Belz's own story of growing as a journalist, as a believer herself, and as a fellow traveler with many of these modern-day heroes of the faith.

Today, Warren Smith talks with Lee and Leslie Strobel about a new movie about their conversion. Lee Strobel is one of the country's best-known Christian apologists and his books, including The Case For Christ, have sold more than 10-million copies. Lee Strobel began his career as a journalist. After receiving a journalism degree from the University of Missouri and a Master of Studies in Law degree from Yale Law School, he worked for The Chicago Tribune and other papers for 14 years. Lee's wife Leslie became a Christian, and that sent Lee on a journey to use his journalistic skills to expose Christianity as a fraud. But his investigation convinced him that Christianity is true, and he also became a Christian.

Today, on the two-year anniversary of the death of Kara Tippetts, we look back on a conversation Warren Smith had with her just months before she died. Kara and her husband Jason had four beautiful children and a thriving new church that Jason started and serves as pastor. But soon after moving to Colorado Springs to start that church, Kara discovered she had breast cancer. Despite aggressive treatment, cancer spread throughout her body. Kara described herself as a terrible sick person. She hated being sick, so it might have been easy for her to retreat into self-pity. Instead, she started blogging about her experiences with a remarkable transparency that immediately won her readers. A publisher discovered the blog, and the result is her first book "The Hardest Peace: Expecting Grace in The Midst of Life's Hard."
