The document discusses how Christians can exercise their spiritual senses through practicing their faith, similar to how physical exercise strengthens the body. It outlines the spiritual counterparts to the five physical senses - taste, hearing, sight, smell, and touch - and provides Bible verses for how to develop each spiritual sense through regular spiritual practices like reading Scripture, prayer, worship, and acts of service. The overall message is that believers should make an effort to continuously train and strengthen their spiritual faculties just as they would their physical senses.
