what does the bible say?
Inaugurated eschatology teaches that the promises of the “last days,” or end times, have already started to be fulfilled. Scripture definitely refers to this current era as “the last days” (Hebrews 1:2), and Peter described the Spirit’s outpouring as the fulfillment of Joel’s prophecy (Acts 2:16–17). Jesus proclaimed the kingdom’s proximity (Mark 1:15) and even said it was already “in your midst” (Luke 17:20–21 [NIV]). These passages demonstrate how His ministry provided believers with a taste of what is to come. The question is whether these previews are the beginning of the kingdom’s fulfillment, as inaugurated eschatology suggests, or if they are signs pointing forward to a future fulfillment.
It is unlikely that the kingdom has been partially fulfilled. The Bible consistently points to the full blessings of the end as future realities: creation still groans (Romans 8:18–25), resurrection is future (1 Corinthians 15:20–26, 51–52), and the new heaven and new earth come after the final judgment (Revelation 21:1–4). Jesus said His kingdom is “not of this world” (John 18:36), clarifying that today’s spiritual blessings do not replace the visible reign the prophets and apostles expected. Many interpreters therefore understand the promised kingdom as the one described in Revelation 20, when Christ will reign openly on the earth.
