An excellent example of duality is found in a prediction Joel made about the Holy Spirit (Joel 2:28-32 - Joel 3:1-2).

God inspired the apostle Peter to quote from this passage to describe events on the Day of Pentecost, when God founded the Church after Jesus' resurrection (Acts 2:14-21). Miraculous manifestations of God's power through the Holy Spirit did indeed occur then (Acts 2:1-12). But these were only the first fulfillment of Joel's prophecy. The ultimate fulfillment will come at the time of the end and will involve, among other things, the gathering of the nations to God's judgment in the Valley of Jehoshaphat. This did not occur on the Day of Pentecost. So we see that prophecies can be dual.

In a similar fashion, God inspired many other prophecies with dual meanings. They applied as warnings to the Israelites at that time and as warnings to the modern descendants of those same people. The people of Britain, the United States, Canada, Australia and New Zealand and the nations of northwest Europe who represent these people today would do well to heed these warnings.
