Outside of a stone cold miracle – think fire from heaven, raising the dead – this is the greatest tool for believing there is a God and He wrote the Bible.
This is precisely because prediction and fulfillment is a gift from God and was by far the ultimate emphasis of evangelism modeled by Jesus and the Apostles going forward from the birth of the Christian Era (Luke 24).
From the Study:

“…We (already) learned what was foretold of Edom, Tyre, and the Philistines centuries ago, but there remain more than a dozen nations, races, and places targeted by detailed predictions.

God built and is building the evidence with each passing year, to show you that the God who parted the seas, rained fire from heaven, and raised the dead is still active in the nations today and intimately involved in your life…”
