In the lower room of the basement Church, Alexander Reed, a leader of the Grace Baptist Church of Philadelphia, heard Conwell preach when he visited him in Lexington, Massachusetts, and recommended that Conwell become a pastor for his congregation. The official "call" was made on October 16, 1882. This room was later deemed the Lecture Room because the Upper Main Audience Room was yet unfinished. The church building was later dedicated by Conwell on December 3, 1882.
