Deuteronomy records the Shema, a confession of faith that devout Jews still use in their evening prayers: “Hear, O Israel: The Lord our God, the Lord is one. You shall love the Lord your God with all your heart and with all your soul and with all your might” (Deuteronomy 6:4-5).
The significance of the Jewish Shema cannot be overestimated. As one of three monotheistic religions, Judaism declares that God is a plurality in unity, also known as the holy trinity—Father, Son, and Holy Spirit. One God expresses Himself in three distinct persons and personalities.
By reciting the entire Shema, devoted Jews profess their monotheistic faith, declare their loving allegiance to the Lord, and commit themselves to the study of the Torah.
