I had a chance to look at the two links you provided.
From what I gathered from the second link, their argument in a nutshell goes something like this.
In the Old Covenant the Jews were saved by faith in God that He would provide the Messiah to redeem them.
Therefore those that have never heard the Gospel before in this day and age are saved in the same way.

With those things in mind, I could answer their logic in a number of ways. Not the least of which is the fact that we are no longer in the Old Covenant and the Messiah has already paid for the sins of the elect.
So I ask you this question. Are people who are of Jewish descent saved if they are still waiting for the promised Messiah (no matter how sincere they are) and don't believe that Jesus is the Messiah?
The answer to that question leads us right back to John 14:6, that Jesus is the only way one can be saved. This would include both those of Jewish descent and those who have never heard the Gospel.

I thought I would also mention something else from the second link.
The author used stories from the book 'Eternity in Their Hearts' by Don Richardson to support his arguments. However, I believe that rather than support his arguments, the stories actually destroy them.
In each story about tribes etc... that became Christians. Each person was converted after they heard the Gospel, not before. Regardless of whether or not they were waiting for a missionary to come and proclaim the Gospel to them.
In other words, they were converted when they put their faith in Jesus Christ.
