When Jesus ascended to heaven and sat down at the right hand of God the Father, He poured out His Holy Spirit at Pentecost. This significant historical and redemptive event was not the last time Christ poured out His Spirit in redemptive history. Mindful of these subsequent acts, Pentecostal Outpourings presents historical research on revivals in the Reformed tradition during the eighteenth and nineteenth centuries. Investigating the British Isles, it observes the outpourings experienced among Welsh Calvinistic Methodists, Irish Dissenters, Calvinistic English Baptists, and Scottish Presbyterians. It then moves on to evaluate the revival instincts among Presbyterians, Congregationalists, Baptists, and the Dutch Reformed in America. May the knowledge of these outpourings of the Holy Spirit help us seek God earnestly to revive His Church once again.
