Muslims believe that Jesus is not God and that calling on Him for salvation is not necessary.

In Romans 10:9-13, the Apostle Paul emphasizes the necessity of confessing Jesus as Lord for salvation, directly linking this to Old Testament prophecies about calling on the name of Yahweh. He quotes Joel 2:32, which states that everyone who calls on the name of Yahweh will be saved, and applies this directly to Jesus, indicating that He is the one who saves. Furthermore, in 1 Corinthians 1:2, Paul refers to Christians as those who call on the name of the Lord Jesus Christ, reinforcing the idea that calling upon Jesus is equivalent to calling upon Yahweh. This connection is further supported by Isaiah 28:16, where the precious stone, a metaphor for salvation, is identified with Yahweh, and Paul applies this to Jesus. Thus, the New Testament consistently presents Jesus as divine and essential for salvation, countering the Muslim claim that He is not God.
