Muslims might say that the New Testament does not clearly present Jesus as God or equate Him with Yahweh.

The Synoptic Gospels provide significant evidence of Jesus' divine preexistence and His identity as God. For instance, in Malachi 3:1, the prophecy speaks of a messenger preparing the way for the Lord, which Christians interpret as John the Baptist preparing for Jesus. This connection is reinforced by Jesus' own identification of John as the messenger in Matthew 11:10. Furthermore, the term 'Lord' in Malachi is understood to refer to God, and since Jesus is equated with this 'Lord,' it suggests His divine status. Additionally, Isaiah 40:3 speaks of preparing the way for Yahweh, which is directly applied to Jesus in Matthew 3:3. This identification of Jesus with Yahweh is not isolated; it appears throughout the New Testament, indicating that Jesus is not merely a prophet but is indeed divine. The consistent theme of Jesus being the fulfillment of Old Testament prophecies further solidifies the argument for His deity. Moreover, the New Testament writers often draw parallels between Jesus and God, suggesting that the kingdom of God and the kingdom of Jesus are one and the same. This theological framework indicates that the New Testament does not present Jesus as a mere envoy but as the divine Messiah who establishes a new covenant, as seen in passages like Matthew 26:28 and Hebrews 8:8-13. Thus, the evidence from both the Old and New Testaments supports the claim of Jesus' divinity and His role as the fulfillment of God's promises.
