The Bible Decoded..

The Philistines were opposed to spiritual discipline. Here they represent foreign thoughts or deviations from a true course, non-spiritual concerns related to the five senses; these detract a person from their spiritual consciousness. These desires must be controlled for spirituality to grow in the soul. You might say the spiritual has to overcome the material, or that “truth must overcome errors in living”.

Goliath the giant represents a major obstacle keeping the spiritual self from growth. David, the spiritual side, must overcome this obstacle in order to control the errant sensory thoughts (Philistines). The rock he uses represents spiritual truth and faith, which when used properly (with the sling of assurance and self-confidence) can overcome the major obstacles to growth.

The material side is more evident and at first exerts a stronger pull than the spiritual, hence the giant in the parable. People may be addicted to money, food, power, violence, sensuality, any number of things of a non-spiritual nature; once something becomes a habit, it takes much spiritual assurance, confidence, and faith to overcome it.
