The quote from C.S. Lewis's "The Great Divorce" emphasizes that natural feelings should not be categorized as inherently good or bad. Instead, their moral value is determined by the influence of God's guidance. When these feelings align with divine will, they are considered pure and holy. However, when they become self-directed and are treated as idols, they can lead individuals astray.

This perspective highlights the importance of recognizing the role of divine oversight in our emotions and desires. Without God's direction, even the most natural feelings can distort into something harmful. Thus, the key is not to suppress these feelings but to ensure they are integrated into a faithful relationship with God.
