So much better than the movie. The movie removed the best and essential part of the story -- Christianity. I cried throughout the entire book. Every time the husband is going through difficult times where he doesn't see much light of life, he thinks about God and he knows God is there for this lovely couple regardless, God is testing them, God is using them to show grace to the rest of the world, God is demonstrating his love through the solid marriage He created. You know the essential element to create a high quality marriage -- trust in God, obey His words.
