A good sermon should leave people thinking about God rather than how long it took you to prepare it, but still, the question does arise. Some people have a very definite view on how long sermon preparation should take: a certain number of hours for a certain length of sermon. In reality, life is not so simple. Here are several factors to keep in mind:
A. A shorter sermon may take longer to prepare. We can’t just say it takes an hour for every minute of sermon, or whatever. In reality I can preach an hour long sermon fairly easily, but a twelve minute sermon takes much more effort to craft.
B. Every sermon is different. One passage may be effectively new ground for me to study, while another passage may be very familiar from previous teaching and preaching ministry. One congregation may feel straightforward, while another, or the same one on another week, may feel like a minefield of potential traps to carefully navigate.
C. It is impossible to measure the pre-study. I might take however many hours to work on a message for this Sunday. But what about the time I took on the same passage some years ago? What about the years of life experience and study of other related passages? What about the years I spent in the classroom laying a foundation of understanding? There really is a lifetime feeding into any sermon.
D. No preacher lives in a vacuum. Real life happens, which means preparation is never predictable. Even if you plan well, the realities and crises of church, family and home have a habit of crowding in anyway. There will be times when we all have to stand and preach with a profound sense of preparation deficit (and that is not something that it generally helps to broadcast in your introduction).
I suppose it is worth asking the question: who is asking the question?
If a listener has appreciated the sermon and is interested, figure out how to accept the encouragement of their appreciation and turn the focus back onto the object of your sermon. Don’t let your ego jump into the conversation and hold centre stage. It really isn’t about you, is it?
If a church is asking the question because they want to know what is appropriate to give by way of reimbursement for time invested, then perhaps ponder these quick thoughts: (1) Preaching has cost the preacher, so reimburse generously. (2) If you are unable to reimburse generously, rest assured that all good preachers are motivated by serving God rather than gaining income (but it might be kind to be honest with them ahead of time – they do have bills to pay too). (3) If the preacher is asking about how much they will receive, or setting a fee, usually this indicates something is not right. Be wary. (4) If you are worried about being too generous, remember that the preacher can always give excess funds away (and if you don’t trust them to be good stewards of money, why are you letting them near the pulpit anyway?) You probably don’t withhold business from an optometrist, a plumber, or a surgeon in case they end up with too much, so why hesitate to be generous with a preacher?
If a preacher is asking the question about time, then I am hesitant to give a definitive answer. What if he simply can’t dedicate the time that I can? What if he needs to dedicate longer to be ready? Here is a simple two-part answer:
1. As much time as it takes – to prayerfully select a passage, study the passage in context, determine passage purpose and idea, then evaluate congregation, define message purpose, craft the message idea, design the preaching strategy (outline) and fill in the details, then also prayerfully preach through the message a few times. Realistically that could add up to quite a bit of time.
2. As much time as you have – You must take into account the reality of life: ministry pressures, other responsibilities, leaking pipes, family illnesses, hospital visits with your injured child, late night crisis counseling with dear friends in marital meltdown, and so on. God knows about these things and perhaps sometimes allows them to keep us from trusting in our preparation routine. If you procrastinate preparation and only take a couple of hours, that’s between you and the Lord (in which case, repent and get things right before moving forward!) But if life hits and you honestly only have limited time, God surely knows and will carry you through.
One thing that I know from many thousands of hours of sermon preparation over the years. It may be a struggle, even a battle at times, but every moment is a privilege.
