"Isaiah Birt’s ministry in Plymouth lasted over 30 years. About 1815, he moved to Birmingham, where his son in the faith and dear friend, Samuel Pearce, had pastored until his death in 1799. For a dozen years, Birt ministered to this body of believers, preaching “only twice on the Lord’s Day” but also on many weekday evenings. Eventually, physical weakness made this impractical. Then he stepped down, moved to London, and preached for others as he was able."
