Through the lips of a sinful preacher, the triune God is actually judging, justifying, reconciling, renewing, and conforming sinners to Christ’s image. God created the world by the words of his mouth and by his speech also brings a new creation into being. In other words, through the proclamation of his Word, God is not just speaking about what might happen if we bring it about but is actually speaking it into being. - Michael Horton
