I preach from the RCL each week. I currently use the A Preacher's Guide for Lectionary Sermon Series. Would be worthwhile in the future if there was media and other resources aimed at Lectionary suggested Scripture.
- One place we provide lectionary content is the featured Thematic Outlines and the Featured Media on the main Sermons.Faithlife.com page. They are both updated each week and items are selected that relate to the verses coming up in future weeks for several lectionaries, including the RCL. Each section has 2-3 items for the upcoming week and then 1 for each of the next three weeks. Have you looked at those? How far out do you typically do your sermon preparation?
