As Christians, when we witness to people, they so often throw lots of questions at us, and they want answers. Now.

Author Mark Cahill spends much of his time looking for creative ways to witness to people about their need for Jesus Christ. His first book, One Thing You Can't Do In Heaven, is full of those ideas. But along the way, he has had more than his share of questions from unbelievers who need something more before they can believe on Jesus Christ.

They ask, How can you be certain there is a God? Is hell a real place? Didn't we really evolve from monkeys? Why should I believe the Bible? So Cahill wrote One Heartbeat Away, filled with answers to the questions that people ask.

Cahill has a gift - an ability to write with an emotional, persuasive style that keeps you eager to turn the page. Whether you are a non-Christian looking for answers, or a Christian looking for a way to answer your friends, you'll be hooked once you start. And you just can't escape being confronted with one of Cahill's favorite questions, "When you die, what do you think is on the other side?"

Read it. Enjoy it. But then give it away.

Some churches are ordering cases of One Heartbeat Away. They are using the book as a gift to visitors. That way, if they don't come back, they have the truth in their hands.

Many young people have testified to the changes in their life and witnessing after reading one or both of Cahill's books. Here are some examples:

"Your books have helped me witness to over 50 people and give out hundreds of tracts." -J S age 18, Sarasota, Florida

"One Heartbeat Away is an AMAZING book...I really recommend reading it! It is a powerful tool/resource to use in leading your friends to Christ!!" -Shelby Bruce, 15

"I am a Christian and I read the book and use the information to witness others. I talked with someone for about 2 1/2 hours using your examples in the book for proving the Bible is true and that there is a God. After talking with him for that long he got saved and it was an answer to prayer. My name is Mercy Jimenez and I am 14 years old. I will continue to evangelize and use your examples, tips, because they are so helpful. God Bless!"

"I read you're first book last summer and shared it with some of my close friends. It radically changed us forever." Michael M. 17, Early Branch, SC

Cahill has dozens of other testimonies from all ages. One English teacher wrote that she was worried that her 78-year-old mother did not fully understand salvation. She read the book in two days and now is confident of her eternal destiny.

Cahill has discovered that many people today are willing to discuss eternal things if properly approached. His books describe how to engage them in conversation and feed them facts that will have them thinking seriously about their destiny.
