In the larger scheme of things, God has commonly effected this purifying by revival or judgement. Strange though it may seem, there are distinct similarities between the ways of God in revival and in judgment... Because of His very nature, God cannot and will not permit spiritual decline to continue unchecked. He is ever halting and reversing the trend of the times by means of revival - or judgment. Where His people are not prepared for the one, they shut themselves up to the other.
