Through present times
Jesus gave a handful of prophecies during his public ministry that the Gospel would be preached throughout the world, that his teachings would reach people worldwide, including this example:
This Good News of the Kingdom will be preached in the whole world for a testimony to all the nations, and then the end will come. (Matthew 24:14, WEB)
Christianity later became the first religion to spread to people in every continent of the world. It is today the most widespread religion, by far, with a presence in at least 95 percent of the world’s 200 or so countries.
You can read more about this prophecy in Jesus the Prophet, by Ray Konig, and at Before the end comes, the Gospel will be preached to the entire world.
