Okay, let’s get one thing straight right off the top. We are subjective beings. In that the postmodernists are correct. We live locked in space and time. We are subject to our point of view, directed by our experience, our education, our parents, personality, and passions. We cannot escape it.
But this is not to say that there is no objective truth, nor does it suggest that we cannot know it. The very fact of our subjectivity requires there be an Object if there is any meaning in the world. Go back to your high school grammar – subjects point to objects. If we are subjects we must be subject to the Object of our existence.
Here is another thing that postmoderns are correct about. Subjects cannot know the object fully and with complete certainty. Subjects can observe, learn, test, and observe, but they can never be sure that they are fully in possession of all the pertinent facts or have not tainted these facts by things we prefer might be so. We can stumble upon the truth by accident. We can discern the truth through scientific observation. We might even be correct, but we can never be certain that we have achieved either.
Of course, there is another way that the subject could know the truth about the object. The object could make itself available to the subject – and this is exactly what has happened. It is, in fact, the nature of the gospel. It is the grounds upon which we find the voice to preach.
Preachers are not so wise to have been able to overcome the limitations of their own subjectivity in and of themselves. Preachers are not any more powerful in that regard than anyone else. Preachers simply have been given access to the Truth by relating to the Object. God is making himself known to his subjects. He has done it through his Word and he does it now through those who preach his Word.
The point is that subjective beings, by definition crave relationship with the Object of their being. Through preaching we can help to make the reconnection.
