The pastor who chooses each Sunday's text on Friday is not exercising Spirit-led spontaneity. They are demonstrating a planning failure that is costing their congregation depth and their own soul's health. Sermon series planning — mapping out months of preaching in advance — is not a constraint on the Spirit's leading. It is the creation of conditions in which the Spirit's leading can be discerned before you are under the pressure of an approaching Sunday.
This is one of the most significant productivity and quality upgrades available to any preacher, and it costs nothing except the initial investment of several hours of planning time and the discipline to protect it once made.
Why Series Planning Matters
The argument for series planning is both pastoral and practical.
Pastorally, a well-planned series communicates to your congregation that their preacher has a vision for their spiritual formation over time — that the preaching ministry has intention and direction, not just week-to-week reaction. Series create anticipation. Congregants know what is coming and can prepare themselves. They begin reading ahead in a book. They start thinking about the question the series is addressing. This anticipation produces a congregation that arrives on Sunday having been engaged all week, which dramatically changes the quality of receptivity.
Practically, advance planning is one of the most significant time-savers a preacher can build into their ministry. The pastor who knows they will be preaching through Philippians for the next eight weeks can do significant research and structural work on the entire letter once, rather than reinventing the contextual and historical framework each week. Books can be ordered, series graphics can be designed, and music or worship themes can be coordinated with the preaching — none of which is possible when texts are chosen a week at a time.
The Annual Planning Session
Once a year, set aside a half-day or full day for sermon planning. This is not the same as sermon preparation. It is sermon series planning — the macro-level work of mapping out what you will preach over the coming twelve months.
Bring to this session:
- A map of your liturgical calendar, noting the key seasons (Advent, Lent, Easter, Pentecost) and any significant church events
- A sense of your congregation's current spiritual season — what are the challenges, the questions, the growth edges?
- A list of the books of the Bible or themes you have been sensing call to preach
- Awareness of gaps in your recent preaching — genres you have not addressed, theological themes you have underserved, congregational needs you have not yet addressed directly
The output of the annual planning session is a draft preaching calendar: a rough map of what series you will preach in each season of the year, with approximate start and end dates and the primary book or theme for each series.
The Quarterly Review
The annual plan is a map, not a contract. Life in a congregation changes. Pastoral needs arise that could not be anticipated. Cultural moments demand a biblical response. The quarterly review — a shorter check-in of an hour or two — allows you to revise the annual plan in light of what has emerged.
The quarterly review also allows you to begin more detailed preparation for the series coming in the next quarter. By the time you begin preaching a series, you should have already:
- Read the entire book of the Bible (for expository series) with initial observations noted
- Identified the natural pericope divisions and the approximate number of sermons the series will require
- Researched any significant historical or theological background material
- Had a preliminary sense of the overall arc of the series — the theological journey from first sermon to last
Designing a Series with Arc
The best sermon series are not simply a collection of sermons on related topics. They have an arc — a theological or narrative journey that builds over the series, creating cumulative depth and momentum.
When planning a series, ask:
- What is the overall theological destination? Where do I want the congregation to be, in terms of understanding and conviction, when this series concludes?
- How should the individual sermons build on each other? Does understanding Sermon 4 depend on having heard Sermons 1-3?
- Where in the series should the most challenging material appear? (Usually not first — early sermons establish trust; later sermons can ask more of the congregation.)
- Where should the resolution or climax appear? (Usually two-thirds through, with the final sermon(s) focused on the implications and applications of what has been established.)
A series with a clear arc keeps congregational engagement high over multiple weeks. People come back because they sense the series is going somewhere.
Series Length
There is no ideal series length, but there are guidelines worth following.
Series shorter than three weeks are often too brief to develop genuine depth or create meaningful anticipation. Series longer than twelve weeks risk losing momentum and exceeding the average congregant's capacity for sustained engagement with a single theme.
For most congregational contexts, series of four to eight weeks strike the best balance — long enough for real depth, short enough to maintain energy. Longer series (ten to sixteen weeks) work best when they are preaching through a book that naturally sustains that length (Romans, John, Psalms) and when the congregation has been prepared for the commitment.
Selecting and Balancing Series
Over the course of a year, most preaching calendars will benefit from a mixture of:
- At least one sustained expository series through a complete book
- At least one topical series addressing a pastoral need or contemporary question
- Seasonal series aligned with the liturgical calendar (Advent, Holy Week/Easter)
- Variety in Old and New Testament, in genre (narrative, epistle, poetry, prophecy), and in theological emphasis (grace, discipleship, mission, community, prayer)
This variety ensures that the congregation receives the full range of biblical teaching and that your own growth as a preacher is not confined to your favorite genres and themes.
Tools like RhemaAI can assist with the planning phase — helping you identify series structures, map out expository series from a book's natural divisions, and think through the arc and balance of a preaching calendar. The planning investment, made once a year and maintained quarterly, will repay itself in calmer weeks, deeper sermons, and a congregation that is genuinely growing together.
Plan the work. Work the plan. And trust that the God who is at work in the preaching of his Word is also at work in the planning.
