Our father Abraham is called ha-ivri (הָעִבְרִי) – “the Hebrew,” a term that means “one who has crossed over” (עָבַר) from another place (Gen. 14:13). The famous medieval Torah commentator Rashi literally identified this “other place” as Ur Kasdim (אוּר כַּשְׂדִים), located east of the Euphrates River, though the midrash (Genesis Rabbah) spiritually identified it as the realm of idolatry: “The whole world stood on one side, but Abram crossed over to the other.” Abram separated himself from a world steeped in idolatry and polytheism by worshipping One God who is the sole Creator of all things…. Understood in this way, being “Hebrew” means being regarded as an “other,” a “stranger,” or an “outsider” to idolatrous worldly culture. Therefore all those who “cross over” from the realm of death to life because of Yeshua are rightly called “Hebrews” (John 5:24).
The term “Jew,” on the other hand, refers to one who praises the LORD (יְהוּדָה). The word (יְהוּדִי) comes from a root (יָדָה) which means to “confess” or to “praise” God (Gen. 29:35). The Apostle Paul alluded to this by saying that one whose heart has been circumcised by the Spirit is “one who is praised by God — not by men” (Rom. 2:29). Being a Jew therefore means you are “chosen” to receive blessings and grace to live in holiness for the glory of God and for the healing of the world. The performance of various mitzvot are for the greater purpose of tikkun olam, the “repair of the world,” in order to reveal God’s goodness and love (Eph. 2:8-10). Doing so makes someone a Jew, since his praise comes not from man, but from the LORD. God is the source and the power of what makes a true tzaddik (righteous person). After all, Israel was meant to be a “light to the nations” (Isa. 42:6; 60:3), and God had always planned for all the families of the earth to come to know Him and give Him glory through his chosen servant Abraham (see Gen. 12:3; 22:18). “Jewishness” is therefore not an end in itself but rather a means to bring healing to the nations… Indeed, the entire redemptive story of the Scriptures centers on the cosmic conflict to deliver humanity from the “curse” by means of the “Seed of the woman” who would come. The gospel is Jewish because it concerns God’s great redemptive plan for the whole world (John 3:16; 4:22).
