Israel was declared a nation in 1948 AD. Jerusalem was declared the capital of Israel in 2017 AD
From the teaching of Apostle Mary Banks

In 1948 Israel was declared a nation once more, and in 2017 Jerusalem was declared its capital. For centuries the Jewish people had been scattered among the nations, yet the Lord had spoken through the prophets that He would take the children of Israel from among the heathen, whither they be gone, gather them on every side, and bring them into their own land.
Scripture does not name these dates, and the fullness of Israel's restoration belongs to the reign of Christ, when the nation is cleansed and all Israel shall be saved. But the return of the Jewish people to their land, with Jerusalem in their hands, sets the stage for what the prophets foretold for the last days: the temple rebuilt in Jerusalem, the covenant the Antichrist makes and breaks, and the holy city trodden under foot by the Gentiles for forty and two months.
The Lord said that in that day He would make Jerusalem a burdensome stone for all people. The city stands at the center of the end time timeline, the place of both the final rebellion against God and the final restoration of His people. Believers are called to pray for the peace of Jerusalem and to watch, for God has not forgotten His covenant.
The scriptures
And say unto them, Thus saith the Lord GOD; Behold, I will take the children of Israel from among the heathen, whither they be gone, and will gather them on every side, and bring them into their own land: And I will make them one nation in the land upon the mountains of Israel; and one king shall be king to them all: and they shall be no more two nations, neither shall they be divided into two kingdoms any more at all:
And it shall come to pass in that day, that the Lord shall set his hand again the second time to recover the remnant of his people, which shall be left, from Assyria, and from Egypt, and from Pathros, and from Cush, and from Elam, and from Shinar, and from Hamath, and from the islands of the sea. And he shall set up an ensign for the nations, and shall assemble the outcasts of Israel, and gather together the dispersed of Judah from the four corners of the earth.
And in that day will I make Jerusalem a burdensome stone for all people: all that burden themselves with it shall be cut in pieces, though all the people of the earth be gathered together against it.
And there was given me a reed like unto a rod: and the angel stood, saying, Rise, and measure the temple of God, and the altar, and them that worship therein. But the court which is without the temple leave out, and measure it not; for it is given unto the Gentiles: and the holy city shall they tread under foot forty and two months.
For I would not, brethren, that ye should be ignorant of this mystery, lest ye should be wise in your own conceits; that blindness in part is happened to Israel, until the fulness of the Gentiles be come in. And so all Israel shall be saved: as it is written, There shall come out of Sion the Deliverer, and shall turn away ungodliness from Jacob:
Pray for the peace of Jerusalem: they shall prosper that love thee.
