God explains why He has chosen the Congregation of Israel here:

Deuteronomy 7:6-9New King James Version (NKJV)

6 "For you are a holy people to the Lord your God; the Lordyour God has chosen you to be a people for Himself, a special treasure above all the peoples on the face of the earth. 7 The Lord did not set His love on you nor choose you because you were more in number than any other people, for you were the least of all peoples; 8 but because the Lord loves you, and because He would keep the oath which He swore to your fathers, the Lord has brought you out with a mighty hand, and redeemed you from the house of bondage, from the hand of Pharaoh king of Egypt.

9 "Therefore know that the Lord your God, He isGod, the faithful God who keeps covenant and mercy for a thousand generations with those who love Him and keep His commandments;
