Muslims believe that Jesus cannot be Yahweh because Yahweh is the one true God and Jesus is a prophet.

The New Testament frequently applies Old Testament passages that refer to Yahweh directly to Jesus, indicating that the authors viewed Him as the divine incarnation. For instance, the act of calling upon the name of the Lord for salvation, which is attributed to Yahweh in Joel 2:32, is echoed in Romans 10:13 where it is stated that everyone who calls on the name of the Lord Jesus will be saved. This parallel suggests that Jesus holds the same divine authority as Yahweh. Moreover, in Acts 7:59-60, Stephen calls upon Jesus as he is being martyred, which further illustrates the belief in Jesus' divine nature. The early Christians, including the apostles, recognized Jesus not merely as a prophet but as the Lord who possesses the same attributes as Yahweh. This is reinforced in 1 Corinthians 1:2, where believers are said to call upon the name of our Lord Jesus Christ, equating Him with the divine. Thus, the New Testament's consistent application of Old Testament references to Yahweh to Jesus supports the Christian claim that Jesus is indeed Yahweh incarnate. This understanding is foundational to the Christian faith and highlights the belief in the Trinity, where Jesus is fully God and fully man, fulfilling the role of Savior as prophesied in the Old Testament.
