Asking only questions, and letting the Bible show the answer, you can convert people to Jesus Christ!
Jesse Ellison was asked questions about the Bible by a friend. Each time he answered, the friend would then show him what the Bible said. This method of asking questions, and letting God provide the truth, brought him to Christ, and he has been on fire for the Lord ever since, with a strong desire to help others come to Christ.
This book is meant to be used as a Bible study tool with someone who you want to reach with the gospel. It has received high praise from those who have put it to use!
