Do Jews worship the same God as Christians and Muslims?

Yes, Jews, Christians, and Muslims all worship the same God in the sense that they all worship the God of Abraham, and are called Abrahamic religions, though they understand God very differently. All three monotheistic faiths trace their origins to Abraham and believe in one God who created the universe, revealed himself to prophets, and calls people to moral living. Judaism worships God as Yahweh, an indivisible, incorporeal, eternal God who made a covenant with Israel. Christianity worships the same God but believes God is a Trinity, Father, Son, and Holy Spirit, with Jesus as the divine Son and Messiah, which Judaism does not accept. Islam worships Allah, which is Arabic for God, and Muslims believe Allah is the same God worshiped by Jews and Christians, but with a final revelation through Muhammad, and they reject the Trinity and divinity of Jesus. So while the object of worship is historically the same God of Abraham, the theology differs significantly. Jews, Christians, and Muslims would agree they worship one Creator God, but Jews and Muslims would say Christians have added incorrect beliefs about Jesus, and Christians would say they have the fullest revelation of that same God through Christ. Many theologians say same God, different understandings, while others emphasize differences are so great that conceptions are not identical.

Jews, Christians, and Muslims are all considered Abrahamic monotheistic religions that trace their spiritual lineage to Abraham and worship one God, so theologically they worship the same God conceptually, though understandings of God's nature differ significantly among traditions, leading to debate. Judaism worships one indivisible God, Yahweh, who made covenant with Abraham and Moses, emphasizing strict monotheism without Trinity. Christianity worships one God in three persons as Trinity, Father, Son, and Holy Spirit, believing Jesus is divine Son of God and second person of Trinity, which Judaism and Islam reject as incompatible with pure monotheism, so Christians believe they worship same God as Jews but revealed as Trinity, while Jews do not accept Trinitarian view. Islam worships Allah, Arabic word for God, one God without partners, with strict monotheism called Tawhid, believing Allah is same God who spoke to Abraham, Moses, and Jesus as prophets, but final revelation through Prophet Muhammad in Quran. All three trace to Abraham, called Ibrahim in Islam, and share many prophets, stories, and ethical teachings, and refer to God as Creator of universe. Many theologians and interfaith dialogues say they worship same God with different interpretations, while some adherents disagree due to doctrinal differences about Jesus divinity and Trinity. So conceptually yes, same God of Abraham, but understandings differ, with Jews and Muslims emphasizing absolute oneness, Christians emphasizing Trinity, making it same God in origin but different theology.
