Fear is a vital survival response that has been also increasingly seen as undesirable by many. Certainly it is unhealthy to be paralyzed by fear. But fear is our God-given warning system for the dangers that are part of living in society and ecosystem. Healthy fear gives a friendly warning before we trample on something precious and breakable. The best defense against always being afraid is learning how to fear wisely what to fear, how to muster courage in the face of fear, and when to tell yourself there's really nothing to be afraid of.
Pride is self-interest plus contentment, guilt is distress plus fear, and perhaps shame.
All our affect responses and feelings are valuable in relationship, in clarifying values, and in self-defense. They are part of our survival equipment. Each can be handled in healthy and unhealthy ways. Learning healthy ways to use them to respond to life is part of growing in wisdom and skill for living. Emotional growth is lifelong.
