From one of my favourite books:

‘… if eschatology is concerned with the reaching of a goal, then there can in principle be no eschatology in the Old Testament. It is only possible in and through the history of Jesus Christ’. – Adrio König, Here Am I: A Believer’s Reflection on God (Grand Rapids/London: Wm. B. Eerdmans/Marshall Morgan & Scott, 1982), 170.
