It's Monday morning and you just received your Pastor's sermon notes and ideas for the week. You have a pastor that rarely plans his message themes and titles ahead more than a few times per year. And when he does, they are as vague as randomly opening the Bible for a reading session.
What do you do?
I get this all the time where I currently serve. While I'd like to say that I have the dream job of having everything 3-4 weeks out ... I rarely get anything more concrete than the week of. I don't despise this though. We are a church that follows a Lectionary cycle, and my Pastor's personal philosophy is: "If it's about Jesus, Communion, God, The Holy Spirit, A Creed, Confessional... it's all good!" With that I can plan a wide variety of services.
I suggest, you first get a lectionary and try to stick to common themes and ideas. Most lectionary programs now actually work within the broader scope of themes. You also have the seasons of the church year. If you do not use Lectionary or The Church Year cycles, then you may want to plan based on you hymnal or use a hymnal for more sturctured planning before you fill in with praise/modern songs.
Blessings as you try to plan your week.
