Strong Convictions

I can't decide whether strongly held convictions inspire or frighten me more. The underlying arrogance of the, "I'm right and you're wrong," starting point of any conversation is troubling for what a unilateral power grab such an assumption represents. On the other hand, the insipid passivity of withdrawing from the conversation altogether in the name of tolerance or relativity or respect smacks too much of excuse-making and conflict avoidance.
Where is that bracing edge where conviction and inquiry, passion and hospitality, living boldly and learning humbly mingle, if not comfortably, then constructively? The stakes are so high when it comes to matters of life and family and work that the conversation absolutely must, regardless of the dangers, be engaged, with all welcome and none retreating.
