To be distinctly fulfilled

I have the impression that the fulfillment of the prophecies in the book of Revelation will be distinct rather than vague. When those things happen any who are familiar with the words of John and looking for his revelation to be fulfilled will recognize the fulfillment and understand his words when they come to pass.

I am fascinated by the knowledge that there will be great upheaval after the seventh seal is opened before the coming of Christ in His glory.
