Few listened to Jesus. As all who read, Saul was going around yanking followers out of their houses and having them beaten up and imprisoned. They as well Murdered the apostles and then the followers. Nero was hanging them up and setting them on fire to light the road to the city, They were put in the colosseum as a public spectacle in with wild animals while the wicked cheered it on. How many followed Jesus when that was occurring? Over a million Israelites were slaughtered 70ad. Romans had the city surrounded but could not break through. The romans left, All who listened to Jesus fled the city. All still followers of The Israelite religion stayed and were slaughtered when the Romans came back. The stories say, no food could get in, they were eating their children.
As the scriptures detailed.........only a "remnant" of the faithful were converted to Christianity. The rest were destroyed because of their "Grievousness" sins against Christ and the truth being delivered from heaven. Jesus warned the Jews that the majority of all Israelites would be lost and Israel destroyed because of their sinful ways. (Luke 19:43-44). In Matthew Jesus makes it clear that this destruction would come in that very generation in the 1st century, "Assuerdly, I say to you, this generation will by no means pass away until all is fulfilled." -- Matthew 23:36, 24:34.
Then Jesus begins to discuss the final judgment upon all mankind. In Matthew 24:35, Jesus warned His disciples that these things would take place (the destruction of Jerusalem and Israel.......then The Christ begins to discuss a question asked by one of His disciples eariler........when will the final judgement come. Jesus told him when He transitioned to the topic of the end of the world...that not even He would know when that day was to come (Matt.24:36). He had just completed giving very detailed information about the destruction of Jerusalem, thus He could not have been referring to the end of the world previously but rather was speaking of the fall of Jerusalem and Isarel. From Matt. 24:36 on Jesus is addressing the end of days or THAT DAY.
He declares that everything would look normal and there would be no warning signs as He had just discussed concerning the fall of Jerusalem. Matthew 24:37-39. Therefore one must be prepared like each day is the last (Matthew 24:42-35)
Jesus warned them of the signs that would come before the destruction of the temple and Jerusalem. This destruction spoken of by Jesus would be limited to Jerusalem and the nation of Israel. (Matt.23 25, Jesus warned and scolded them) in (Matt 24:1-2) Jesus begins to speak to His disciples in describing how very shortly not a stone would be left unturned in the Temple they were looking at.
Biblical Isarel was destroyed in the 1st century.......with its peoples either killed or scattered around the then known world, just as Jesus prophesied and their nation was given to another nation. "The kingdom of God will be taken from you and given to a peoples PRODUCING THE FRUIT OF IT." -- Matt. 21:43. The nation was given to the faithful remnant of the loyal Jews who accepted Christianity.
Modern Israel is nothing like the Israel described in the Bible. There is no God appointed King....modern Israel is ruled over by a man made government. There are no Tribal IDs...........no Royal Tribe of Priests such as the Lev., There are no animal sacrifices annually.....Modern Israel is a mirrored reflection of Israel when you look through it darkly...its a fake created and maintained by MEN.
Is Israel eternally lost? Of course not, all they need do is accept Jesus as the Christ of prophecy, until such time they are just as lost as is any sinner who is not covered in the Blood of Christ Jesus for the remission of sin. There is only one advocate standing between God and man's sin,,,,,,,,,and that is Christ Jesus who stated it very clearly, "Jesus saith unto him, I am the way, the truth and the life: no man cometh unto the Father but by Me." -- John 14:6
