Dr. David Plaster (right), who this week is concluding his service as an administrator at Grace College and Seminary, delivered two keynote addresses yesterday, April 29, at the Iowa/Midland District Conference.

Plaster’s messages, reflecting the conference theme of “In Spirit and In Truth” laid out a solid theology of worship.

Grace College and Seminary will have commencement exercises this weekend, and Plaster will then transition into the senior pastor role at the Grace Brethren Church of Columbus, Ohio, succeeding longtime Columbus pastor Jim Custer.
