The NT is an apocalypse, not a history. NT evidence suggests that the knowledge of Christ's coming was communicated beforehand to preselected witnesses through the agency of the Holy Spirit. It appears, then, that the theological purpose of the gospels is to provide a fitting introduction to the messianic story beforehand so that it can be passed down from generation to generation until the time of its fulfilment. It's as though NT history is written in advance!All Rights Reserved
