Revival in a Christian context refers to a specific period of intense spiritual renewal in the life of the church - the believers in Christ. While elements such as mass conversions may be involved, the key factor in revival is the restoration of the Church to a vital and fervent relationship with God after a period of decline. Since the [[Reformation]], some writers identify six waves of special revival or "Awakenings" in the church worldwide (1727, 1792, 1830, 1857, 1882 and 1904).
