Prophetic perfect tense
The prophetic perfect tense is a verb tense used in the Bible that describes future events that are so certain to happen that they are referred to in the past tense as if they already happened. Only God can speak of events in such a fashon since He alone is able to guarantee their fulfillment. Many liberal scholars contest the existence of this tense, claiming that all of the events ascribed to prophetic perfect can be understood to have indeed occurred in the past.
