One of the main metaphors the Bible gives us for facing affliction is walking – walking through something difficult, perilous and potentially fatal.
The walking metaphor points to the idea of progress. Many ancients saw adversity as merely something to withstand and endure without flinching, or even feeling, until it goes away. Modern Western people see suffering as something like adverse weather, something you avoid or insulate yourself from until it passes by.
The unusual balance of the Christian faith is seen in the metaphor of walking – through darkness, swirling waters or fire. We are not to lose our footing and just let the suffering have its way with us. But we are also not to think we can somehow avoid it or be completely impervious to it either. We are to meet and move through suffering without shock and surprise, without denial of our sorrow and weakness, without resentment or paralyzing fear, yet also without acquiescence or capitulation, without surrender or despair.
