Let Those Who Have Ears to Hear continues the discussion started in the book, Oh, Be Careful Little Ears, with more thought-provoking insights. For example... Did you know that secular rock musicians€ comments about the €œbeat€ support the conclusion that it€s €œmusical pornography€Â? Did you know that rock music is purposely designed to appeal to our carnal self€"regardless of the lyrics? Did you know that there are specific, identifiable musical techniques which €œfeed the flesh€Â? Did you know that contemporary Christian music (CCM) uses these same techniques? You will learn...when drums are €œright€Â; when drums are €œwrong€Â; how the term €œcontemporary music€ applies throughout history and why CCM is different; steps to help you and your family begin to discern music; and much more. This book also gives solid, biblical answers to refute fifty common defenses (excuses) by proponents of contemporary Christian music in the chapter, "What We Believe is Our Truth." Some of the statements answered are: "People are saved at CCM concerts"; "The music makes me feel closer to God"; "Where in the Bible does it say a certain beat is wrong?"; "Psalm 33:3 says we're to sing 'a new song' to the Lord"; "It's all relative; everyone has his or her own tastes," and many more. Eight more chapters which discuss the adverse effects that CCM has had on the Church include: "The Voice of the Harlot," "Cool Is Not a Fruit of the Spirit," and "Where Do We Draw the Line?" Although written as a follow-up to Oh, Be Careful Little Ears, Let Those Who Have Ears stands alone, as well.Â
