To begin with, in today's world you cannot escape the truth of the Gospel. It is all around us, yet many would rather ignore what they hear because they do not have a heart to understand nor an ear to hear.
Plus, ignorance of the Jewish teachers is no excuse. All Jewish Teachers who lived from the time of the prophets on through when Christ walked on the earth and even to this day have known about Christ because the scriptures speak loudly about Him. It's just that they refused to teach their people the truth.
Just like those who belong to a false Christian organization like the Mormons, Jehovah Witnesses etc. etc. They are lost because they were taught lies by their teachers. They had the chance to believe, but they were fed lies. They are lost, but it will be much worse for those who knew the truth yet taught lies, than it will be for those who heard the lies and believed them and thus died in ignorance.
Those who lived in places that have never ever had the Gospel preached to them, yet they died, like the America's before the settlers arrived, or in the middle of the forest jungles of South America, or the orient or Africa before missionaries arrived could be spared if their hearts are pure I guess.
When considering such matters, I am reminded of Ecclesiastes 3:11 where Solomon wrote
"He has made everything beautiful in its time. Also He has put eternity in their hearts".
Have you ever read the book, "Eternity In Their Hearts"? It is a book written in 1981 by, Don Richardson.
The premise of his book is that God has prepared the hearts of all people to accept the Gospel. Some will accept it when they hear it, while some will reject it out of love for the world.
Richardson uses compelling stories from many different cultures to show how the concept of a supreme God has existed for centuries in hundreds of cultures throughout the world. From the jungles of Burma to small tribes in the middle of the Rain Forest of South America. All civilizations have tales passed from generation to generation that has prepared them for the gospel. Just like every culture has some form of the story of the flood, they also have some form of the truth, it's just that through time they have failed to properly pass it on to their descendants and it got a bit skewed.
Now whether or not there were individuals throughout history from places never reached by the Gospel, yet they were like Job who was a Godly man, yet not from Abraham's stock and we all know he was a great servant of God.
However, you specifically speak of the Jews, and the truth is in the scriptures that they have, yet would rather ignore them. Jesus told them,
"You search the Scriptures, for in them you think you have eternal life; and these are they which testify of Me".
You can not have it both ways. Either you are God's chosen and you have the truth and are ignoring it, or you are not God's chosen and He never told you about His coming. In that case maybe one could be saved without hearing the Gospel. As I said though, the Jews have the truth, and reject it. Thus the lord says he will reject all who reject him.
You cannot reject the cornerstone that the Church is built upon and expect to get a mulligan when you come face to face with Him on judgment day.
Agreed! The book of Hebrews says, “God is a rewarder of those who diligently seek Him.” Other passages also state that he WILL be found when we search for Him “with all your hearts”. I also have read of testimonies of people, who for all practical purposes could not have had the gospel preached to them, YET still have believed in the savior sent from God. We limit God - with whom NOTHING is impossible - by asserting nobody can know the gospel unless a missionary tells them. I will not limit God but believe He keeps His promises and all who seek for Him WILL know the truth. If it is God's will that all men be saved and come to the knowledge of the truth, then ANY who He moves to seek Him WILL be rewarded with the truth - even if they live in the deepest, darkest jungles!
