David Wilkerson reflects on King David's weariness and desire for peace amidst struggles, paralleling it with the life of hermit crabs that abandon their fight for survival. He emphasizes that while some crabs seek safety in discarded shells, they ultimately lose their strength and vitality, illustrating the spiritual truth that believers must engage in their struggles to grow stronger in faith. Just as crabs that continue to fight develop resilience, Christians who face their challenges with trust in Jesus find true refuge and strength. Wilkerson encourages believers to embrace their battles rather than retreating into false safety, as true growth comes from enduring hardships.
