Muslims believe that Jesus is not God and that the concept of the Trinity is incompatible with the oneness of God.

In 1 John 5:20, the Apostle John explicitly states that Jesus is the true God and Eternal Life, indicating his divine nature. This claim is further supported by the context of John's writings, where he describes Jesus as the Eternal Life that was with the Father and manifested to humanity. Additionally, throughout the Gospel of John, Jesus refers to himself as the Life and the one who grants eternal life to believers. For instance, in John 11:25-26, Jesus declares, 'I am the Resurrection and the Life,' affirming his role as the source of eternal life. Furthermore, John 17:3 highlights that knowing Jesus is part of knowing the only true God, reinforcing the unity between the Father and the Son. The consistent portrayal of Jesus as divine throughout the New Testament, including John 1:1, where it states 'the Word was God,' supports the Christian belief in the Trinity, which encompasses the Father, the Son, and the Holy Spirit as one God in three persons. Therefore, the biblical evidence strongly affirms the divinity of Jesus, countering the Muslim claim that he is merely a prophet and not God.
