10, 11. When was the major fulfillment of Zephaniah’s restoration prophecy to take place, and how do we know this?

¹⁰ Another restoration took place in the first century of the Common Era, when Jesus Christ gathered a remnant of Israel to true worship. That was a foregleam of what was yet to come, for the major fulfillment of the restoration was still future. Micah’s prophecy foretold: “It must occur in the final part of the days that the mountain of the house of Jehovah will become firmly established above the top of the mountains, and it will certainly be lifted up above the hills; and to it peoples must stream.”​—Micah 4:1.

¹¹ When would this happen? As the prophecy said, “in the final part of the days”​—yes, during these “last days.” (2 Timothy 3:1)

12. How has true worship been elevated in these last days?

¹² In these last days, therefore, “the mountain of the house of Jehovah [has] become firmly established above the top of the mountains.” The lofty true worship of Jehovah has been restored, firmly established, and elevated above any and all other types of religion. As Micah’s prophecy also foretold, “to it peoples must stream.”

13, 14. When did this world enter “the final part of the days,” and what has been happening since then in regard to true worship?

¹³ Events in fulfillment of Bible prophecy prove that this world entered “the final part of the days”​—its last days—​in the year 1914. (Mark 13:4-10) History shows that Jehovah began gathering to true worship a faithful remnant of anointed ones having the heavenly hope. This has been followed by the gathering of “a great crowd . . . out of all nations and tribes and peoples and tongues”​—those who have the hope of living forever on earth.​—Revelation 7:9.

¹⁴ Since World War I and right up to this day, the worship of Jehovah by those who bear his name has moved ahead mightily under his direction. Increasing from a few thousand after World War I, the worshipers of Jehovah now number about six million, gathered in some 91,000 congregations in 235 lands. Each year, these Kingdom proclaimers are devoting well over a billion hours publicly praising God. It is clear that these Witnesses of Jehovah are the ones fulfilling Jesus’ prophetic words: “This good news of the kingdom will be preached in all the inhabited earth for a witness to all the nations; and then the end will come.”​—Matthew 24:14.
