One of the current fads within the church is innovation, marketing, simplification. Now, the Gospel is simple. But applying, it, like many simple things, is incredibly difficult. The teaching elder needs to spend a fair amount of time in exegesis… struggling with his Greek, his Hebrew, and at times his Latin to consider what the text means,
For that does not change. But if he does not preach that, and then apply it to the lives of the congregation, he is not doing his job.
30“I can do nothing on my own. As I hear, I judge; and my judgment is just, because I seek to do not my own will but the will of him who sent me.
31“If I testify about myself, my testimony is not true. 32There is another who testifies on my behalf, and I know that his testimony to me is true. 33You sent messengers to John, and he testified to the truth. 34Not that I accept such human testimony, but I say these things so that you may be saved. 35He was a burning and shining lamp, and you were willing to rejoice for a while in his light. 36But I have a testimony greater than John’s. The works that the Father has given me to complete, the very works that I am doing, testify on my behalf that the Father has sent me. 37And the Father who sent me has himself testified on my behalf. You have never heard his voice or seen his form, 38and you do not have his word abiding in you, because you do not believe him whom he has sent.
39“You search the scriptures because you think that in them you have eternal life; and it is they that testify on my behalf. 40Yet you refuse to come to me to have life.
Now, one of the things that the congregation will do is stray. To that which is comfortable. No one wants to get out of bed and doe the uncomfortable things… but every parent has done this, repeatedly, to a babe. For we in love do what is needed.
(Note: there is nothing, nothing here which is protestant. The reformers already knew how to preach, because those before them had done so for generations.
But if you just do the simple stuff it is like feeding nothing but cheezo. It will assuage hunger, but without substance, you will still starve. A good test is reproof — if you are not confronting your own sin and those around you are not doing your job.
This sheep, you see, is starving. He needs to be fed. Fortunately, he can read… but reading theology does not replace solid preaching: we are saved together and we starve together, and you cannot cure this with a mere reading list.
