Prophecy has multiple functions: some is short-term (credentialing for contemporaries), some long-term (evidence for distant generations), some purely theological.

Short-term prophecy (fulfilled within the prophet's own generation) was vital to establish the prophet's credibility for people living at that time. Long-term prophecy is what distant generations need to verify divine inspiration, because only centuries of separation rule out coincidence or educated guessing. Theological prophecy may serve neither role but still illuminates doctrine or narrative.
