The jews were God's chosen people. But they rejected their messiah.
Hebrews 8:7-13
7 For if that first covenant had been faultless, then no place would have been sought for a second. 8 Because finding fault with them, He says: “Behold, the days are coming, says the Lord, when I will make a new covenant with the house of Israel and with the house of Judah— 9 not according to the covenant that I made with their fathers in the day when I took them by the hand to lead them out of the land of Egypt; because they did not continue in My covenant, and I disregarded them, says the Lord. 10 For this is the covenant that I will make with the house of Israel after those days, says the Lord: I will put My laws in their mind and write them on their hearts; and I will be their God, and they shall be My people. 11 None of them shall teach his neighbor, and none his brother, saying, ‘Know the Lord,’ for all shall know Me, from the least of them to the greatest of them. 12 For I will be merciful to their unrighteousness, and their sins and their lawless deeds I will remember no more.”
13 In that He says, “A new covenant,” He has made the first obsolete. Now what is becoming obsolete and growing old is ready to vanish away.
Under the old testament ("first covenant" in this passage), God's chosen people were born into their relationship with God, even though they did not know him at birth. They were raised being told "Know the Lord" because they became God's chosen people at birth, before they knew Him.
That situation is over now. From v13, the new covenant (a.k.a. new testament / the gospel) replaced it. The old covenant relationship is gone now.
Now, people become Christians when they are baptized into their relationship with God. No one is in this relationship with God who doesn't already know Him, which is why v11 says "None of them shall teach his neighbor, and none his brother, saying, ‘Know the Lord,’ for all shall know Me".
The book of Hebrews is directed to the Hebrew (Jewish) people and the book can be summarized as: Jesus is your messiah, you're not getting another one. Going forward, He's your opportunity for salvation.
