Well, it was not back in 70 ad which people who say Matthew 24 was all about that time and not for a future time.
That one thing Jesus says in Matthew 24 should have been enough to convince preterists about Matthew 24 still concerns future events..
The chapter concerns destruction of Jerusalem and when Jesus returns, the end of the age. Jesus has not yet returned in 2021 ad. But preterists will say Jesus returned in 70ad, and returns many times. But scripture talks only about a second coming, not a third, fourth, etc.. coming.
Has not been preached in all nations yet, if you include small tribes as a nation.
how about the Sentinelese people
Sentinelese.
interesting story of someone who went there illegally recently as a Christian missionary. However the Lord did not give him success.
In November 2018,
John Allen Chau, a 26-year-old American,
[75] trained and sent by the US-based
Christian missionary organization All Nations,
[76] travelled to North Sentinel Island with the
aim of contacting and living among the Sentinelese
[76] in the hope of converting them to Christianity.
[75][77][9][78] Chau did not seek the necessary permits required to visit the island
[79][80] and traveled illegally to the island by bribing local fishermen.
[81] He expressed a clear desire to convert the tribe and awareness of the risk of death he faced and of the illegality of his visits, writing, "Lord, is this island Satan's last stronghold where none have heard or even had the chance to hear your name?", "The eternal lives of this tribe is at hand", and "I think it's worthwhile to declare Jesus to these people. Please do not be angry at them or at God if I get killed...Don't retrieve my body."
[82][83][84]
On 15 November, Chau attempted his first visit in a fishing boat, which took him about 500–700 metres (1,600–2,300 feet) from shore.
[81] The fishermen warned Chau not to go farther, but he
canoed toward shore with a waterproof Bible. As he approached, he attempted to communicate with the islanders
[75] and to offer gifts, but he retreated after facing hostile responses.
[85][84] On another visit, Chau recorded that the islanders reacted to him with a mixture of amusement, bewilderment and hostility. He attempted to sing worship songs to them, and spoke to them in
Xhosa, after which they often fell silent. Other attempts to communicate ended with them bursting into laughter.
[85] Chau stated they communicated with "lots of high pitched sounds" and gestures.
[86] Eventually, according to Chau's last letter, when he tried to hand over fish and gifts, a boy shot a metal-headed arrow that pierced the Bible he was holding in front of his chest, after which he retreated again.
[85]
On his final visit, on 17 November, Chau instructed the fishermen to leave without him.
[78] The fishermen later saw the islanders dragging Chau's body, and the next day they saw his body on the shore.
[81]
Police subsequently arrested seven fishermen for assisting Chau to get close to the restricted island.
[84] His death was treated as a murder, but there was no suggestion that the Sentinelese would be charged
[87] and the U.S. government confirmed that it did not ask the Indian government to press charges against the tribe.
[88][89] Indian officials made several attempts to recover Chau's body but eventually abandoned those efforts. An anthropologist involved in the case told
The Guardian that the risk of a dangerous clash between investigators and the islanders was too great to justify any further attempts.
[90] He remains buried on the island.
