Pastors are busy. I know; I was one. They hardly have time to prepare their sermons every week while at the same time visiting, counseling, planning, fixing, etc. Ask most pastors what good theology books they’ve read recently and you’ll be greeted by blank stares. Been there, done that. I often felt that I hardly had time to read my Bible most days, let alone anything else.

Yet, looking back now, I realize I was a bit short-sighted. Most of my agony over the text I was going to preach each week came from a lack of input from great minds of the past and present. I was trying to reinvent the wheel with every sermon. Sure, I was reading commentaries, but I wasn’t reading much theology that would provide the substance and nourishment of better preaching. By not reading theology, I was making my sermon prep more difficult.

I am not advocating the reading of just any theology to nourish spiritual life and preaching. There is no virtue in reading dull or poorly-written theologies. Rather, directed reading of good theologies will provide fodder for thought, clarify difficulties in the text, and sometimes even offer a pertinent illustration of the truth the preacher is trying to communicate.

Cornelius Van Til recognized the value of a pastor reading theology:

What is beneficial for the individual believer [studying systematic theology] is also beneficial for the minister and in consequence for the church as a whole. It is sometimes contended that ministers need not be trained in systematic theology if only they know their Bibles. But “Bible-trained” instead of systematically trained preachers frequently preach error. They may mean ever so well and be ever so true to the gospel on certain points; nevertheless, they often preach error…

If we carry this idea one step further, we note that a study of systematic theology will help men to preach theologically. It will help to make men proclaim the whole counsel of God. Many ministers never touch the greater part of the wealth of the revelation of God to man contained in Scripture. But systematics helps ministers to preach the whole counsel of God, and thus to make God central in their work.

The history of the church bears out the claim that God-centered preaching is most valuable to the church of Christ. When the minister has most truly proclaimed the whole counsel of God, the church has flourished spiritually.

Pastors who study theology do their congregation a great service. Generally their preaching has more substance, and their ideas are drawn from a larger pool of knowledge and exposure than one who does not read. Pastors who do not study theology tend to preach atheological sermons. They may be able to atomistically expound a text, but they will have difficulty connecting the text to the grand redemptive truths that give the texts weighty significance.

Van Til saw a definite connection between the study of systematic theology and the ability to preach the whole counsel of God. If a pastor is not well-versed in theology, he may shy away from Scriptures that his flock needs for growth in grace. Or worse, he may shy away from Scriptures his flock needs for spiritual and doctrinal protection. That will be the subject of tomorrow’s post.
