The Jethro Plan

Plan 12 Sundays in one afternoon

A project manager's way to map a whole series before it starts, milestones and all.

What if you knew what you'd preach or teach for the next 12 Sundays?

For a lot of small-church leaders, that sounds like a luxury. Most weeks, the question "What am I doing this Sunday?" doesn't get answered until Thursday. But planning a quarter at once takes less time than you'd think. In project management, we break a big goal into phases and milestones. You can do the same with a series, in a single afternoon.

Block three hours. Bring a Bible, a calendar, and a pad of paper. Then work through these six steps.

Before you start: pray and listen

In Acts 13, the leaders of the church at Antioch were worshiping and fasting when the Holy Spirit spoke and set apart Barnabas and Saul for the work ahead (Acts 13:1 to 3). The plan grew out of worship.

Spend the first part of your afternoon the same way. Before you open a calendar, open your Bible and pray: "Lord, what do you want to say to our church in this season?" Pay attention to the passages that keep coming to mind and the needs you can't shake. The theme of your series should come from listening to God, not just from analyzing needs.

1. Pick one theme

Start with what your people need in the season ahead. A church walking through loss might need a series on hope. A church that's grown tired might need one on rest. Write the theme at the top of the page in a few words, like "Storms and Faith" or "Life Together."

2. Choose 12 passages

List passages that speak to the theme. You'll probably come up with more than 12, which is good. Cross off the ones that repeat each other until you have 12 that build on one another.

3. Group them into three or four movements

This is where a list becomes a plan. Arrange the passages so the series goes somewhere. For a series on storms, that might look like:

  • Weeks 1 to 2: Jesus in the storm
  • Weeks 3 to 6: Where storms come from
  • Weeks 7 to 9: Courage in the storm
  • Weeks 10 to 12: After the storm

Each movement is a phase. When people can feel the series moving, they come back to see where it's going.

4. Write one sentence for each Sunday

This is the most valuable hour of the afternoon. For each passage, write the big idea in one sentence. You don't need a sermon outline yet, just the one thing you want your people to carry out the door. Later, when a busy week hits, that sentence will already be waiting for you.

5. Mark the special Sundays

Open the calendar and mark every Sunday that won't be ordinary: holidays, baptisms, a guest speaker, a church anniversary, the week of vacation Bible school. Move passages around those days, or plan a stand-alone message that still fits the theme.

6. Set your weekly milestones

A series map isn't finished until you know what "on track" looks like each week. Pick a simple rhythm and write it at the bottom of the page:

  • Monday: read the passage
  • Tuesday: confirm the big idea and send it to your teachers and worship leader
  • Thursday: outline done
  • Saturday afternoon: final polish

If Thursday comes and there's no outline, you know it's time to ask for help or simplify, and you know it on Thursday instead of Saturday night.

Plan for the Sundays that won't go as planned

Every project manager keeps a short list of backup plans. You should too. What happens if snow cancels a Sunday? (Text the week's big idea and a family devotional, then combine the next two weeks.) What if you're sick? (Keep one ready-to-go message from earlier in the series that a trusted leader could share.) Thinking this through once saves a lot of panic later.

Hold the map with open hands

A series map is a servant, not a master. Revisit it every month and ask, "Is this still what God is saying to us?" If the Holy Spirit leads you to a different passage, or a crisis in the church calls for a different word, change the map. James reminds us to hold our plans humbly and say, "If the Lord wills, we will do this or that" (James 4:13 to 15, paraphrased). Planning ahead doesn't close the door on the Spirit. It frees you to notice when he's opening a new one.

Why it's worth an afternoon

When you plan 12 Sundays at once, you stop starting from zero every Monday. Your volunteers can prepare ahead. Your children's teacher knows what's coming. And you get to spend your week thinking about the message instead of hunting for one.

Jesus said a builder sits down first and counts the cost before building a tower (Luke 14:28). A series map is how you sit down first.
