What the Bible says about Salvation is of the Jews
(From Forerunner Commentary)
The patriarch Jacob had twelve sons, and God had to choose from which tribe His Son would descend. He proclaims His choice through Jacob's prophecy in Genesis 49:10: "The scepter shall not depart from Judah, nor a lawgiver from between his feet, until Shiloh comes; and to Him shall be the obedience of the people." Jesus of Nazareth was a Jew, as many scriptures record (Matthew 1:2; Luke 3:33; Hebrews 7:14, etc.).
This fact also has spiritual implications for us. Jesus says to the woman at the well, "For salvation is of the Jews" (John 4:22). Paul explains what this means:
For he is not a Jew who is one outwardly, nor is that circumcision which is outward in the flesh; but he is a Jew who is one inwardly, and circumcision is that of the heart, in the Spirit, and not in the letter; whose praise is not from men but from God. (Romans 2:28-29)

We begin to see a major reason why God chose to provide salvation as He has. In short, He feels that more can be produced toward His purpose by doing it this way than by Him entering into another covenant with another group of people.
