To know whether we have the true historical event for the fulfilment of a prophecy. If you find every word of the prophecy (after the figures are understood) is literally fulfilled, then you may know that your history is the true event. But if one word lacks a fulfilment, then you must look for another event, or wait its future development. For God takes care that history and prophecy doth agree, so that the true believing children of God may never be ashamed. MWV1 22.6
