Interpretation of Nebuchadnezzar's dream the king of Babylon (Daniel 2: 32-48) is fulfilled thus far (Dan 2:32-43).
The Church sealed by the Holy Spirit, that is those who believed in Jesus Christ and have yielded their lives to Him as in Romans 6, will be raptured the moment the tribulation is just about to begin.
The church once raptured, the work of the Holy Spirit, baptizing the person, who calls on the name of the Lord Jesus Christ into Church ceases.Henceforth there is absolutely no grace and no more addition to the church.(The Parable of the Ten Virgins)
Not all the Christians who pray to God and attend Church is called the 'Church'.Only those whose lives are changed from the old sinful habits to a life yielded to Christ by the work of the Holy Spirit. (Matt 7:21-23).
