We live in a dark world. Our hearts long for goodness, beauty, justice, and peace, but they are often hidden behind the shadow cast by evil and sin. This is why preaching is so necessary. Whenever the kingdom of God is proclaimed, it is like a bright burst of light. In those brief moments, the shadows recede and we are given a glimpse of a world behind the darkness. It is a sublime vision that reorders our perception of reality and leaves us hungry for more.
This understanding of preaching, the unveiling of an inspiring vision of God's kingdom, is not the one I've always held. I was formed to think that the primary purpose of preaching was instruction. This view of preaching expects the informed, articulate person behind the pulpit to teach the congregation divine truths and skills. The pupils are then expected to bury these seeds of biblical knowledge away in their brains where in time they germinate into godly values and behaviors, although few people seem surprised when they don't.
