When we study Jesus’ understanding of “kingdom” in the Gospels there are two competing themes. In some texts, Jesus seems to say that the Kingdom of God is present in his ministry. For example, Mark describes Jesus preaching that the Kingdom of God is “near” at the very beginning of his ministry (Mark 1:15, Luke 8:1). In Jesus says that if demons are cast out the hand of God, then the kingdom of God has come (Luke 11:20). Jesus also says that the reason he teachings in parables was to reveal the secrets of the Kingdom to his disciples (Luke 8:10)
On the other hand, it is possible to stress only the future aspect of the kingdom. Someone like Schweitzer, for example, thought Jesus was an apocalyptic prophet who expected a messianic kingdom promised by the prophets of the Hebrew Bible. While Schweitzer thought Jesus was wrong, other streams of theology (such as classic dispensationalism) understands Jesus as teaching a future kingdom, literally fulfilling the promises of the Hebrew Bible, including a restoration of the kingdom to the Jewish people. But a wholly future kingdom does not really do justice to Jesus’ claim that the kingdom is present in his ministry.
A third option is to see Jesus’s ministry as a present kingdom, but a kingdom which does not exhaust the prophecies of the Hebrew Bible. This has the advantage of taking Jesus seriously when he says that his miracles are establishing some sort of kingdom, but also the warnings of a lengthy interim between the establishment of the kingdom and the consummation of the kingdom in the (now distant) future.
The catch-phrase “already / not yet” is perhaps so overused that it has lost all rhetorical value, but it remains a fairly good way of understanding the kingdom in the gospels. Some elements of the kingdom expected by the prophets is present in Jesus’ ministry, but others remain unfulfilled until a future time. The point is the present church lives “between the ages,” after the “already” but before the “not yet.” We look back to the death and resurrection of Jesus, but also forward to the future consummation of the ages.
Are there other specific sayings or actions of Jesus where the “already / not yet” may help our understanding of the text?
