As a young man, Josh McDowell considered himself an agnostic. He truly believed that Christianity was worthless. However, when challenged to intellectually examine the claims of Christianity, Josh discovered compelling and overwhelming evidence for the reliability of the Christian faith. After trusting in Jesus Christ as Savior and Lord, Josh’s life changed dramatically as he experienced the power of God’s love. After his conversion, Josh committed his life to telling a doubting world about the truth of Jesus Christ. After studying at Kellogg College, Josh completed his college degree at Wheaton College and then attended Talbot Theological Seminary, graduating magna cum laude with a Masters of Divinity. Working with Campus Crusade for Christ and founding the youth outreach, Josh McDowell Ministry, Josh has shared the gospel with more than 25 million people in 125 countries. He is the author or co-author of 147 books.
