This week's reading from Acts has so many points of entry, it's hard to choose. Identity? Inclusivity? God's grace in the world? Go with the last for a moment. Depending on the translation, following his vision, Peter can neither "hinder" or "withstand" God's grace. Those are words almost of struggle, as if God's grace is so integrally woven into our world that we actually have to work hard to overcome it.
Perhaps you'd rather preach on Revelation. I dont know about you, but I find the promises of heavenly city so perfectly beautiful, that there seems nothing more to add. How will you preach on it?
Going with psalm ("hey, it's ALL good!") or the gospel ("all you need is love") instead? Wherever you are heading, you cant escape God's work in the world this week.
