All prophets get a revelation of the heart of man and so are enabled to project the arc of their destruction based on the tools at their disposal, some with more precision than others. The extent of an element of the population having connection with the Creator determines how precipitous the destruction comes.
Those prophets who get a revelation of the Lord Jesus Christ understand the New Spirit potential and so are able project the arc of glory which each affected life may take. The extent of the believer`s attainment of glory is a function of their submission. The extent of the body`s attainment of glory is a function of our corporate submission.
Some prophets get definitive, precise information on events that will happen. Such prophets are those who are held to the high standard of accuracy. If their specific prophecy does not come to pass, they are deemed false prophets.
