It astonishes me how many Christians watch the same banal, empty, silly, trivial, titillating, suggestive, immodest TV shows that most unbelievers watch – and then wonder why their spiritual lives are weak and their worship experience is shallow with no intensity. If you really want to hear the Word of God the way He means to be heard in truth and joy and power, turn off the television on Saturday night and read something true and great and beautiful and pure and honorable and excellent and worthy of praise (see Philippians 4:8). Then watch your heart unshrivel and begin to hunger for the Word of God.
