Based on Lord Jesus' words on the cross "It is finished," pastors and elders of religious circles habitually conclude that God's work of salvation of mankind was thus finished. Upon the return of the Lord, believers would be received into the kingdom of heaven, with no need for any work of purifying and saving people. Does the viewpoint of the pastors and elders accord with the words of God? To what was Lord Jesus ultimately referring, when He said "It is finished" on the cross? Why would God want to express truth during the last days, doing the work of judging and purifying people?
