As in Paul’s day, we today are engaged in a great battle of ideas. Systems of thought that are part of our culture are posing serious threats to those who hold to a biblical world view. Walking by faith becomes increasingly difficult in the face of these challenges. Young Christians, especially, often find themselves facing difficult questions regarding their faith and are looking for help with their answers. The lessons in this series examine common challenges to the faith of Christians—especially young Christians. Some of these challenges have to do with the authority and integrity of the Bible, the uniqueness of Christianity, ethics, and morality, and intellectual and social tensions of our culture. The speakers have provided some valuable help in dealing with these challenges.
