Muslims often argue that the concept of Jesus as a sacrifice for sins contradicts the oneness of God, as it implies a division within the Godhead.

The New Testament clearly teaches that Jesus was appointed as our High Priest, who presented himself as a sin offering for humanity. In Hebrews 3:1, Jesus is acknowledged as our apostle and high priest, emphasizing his role in mediating between God and mankind. Furthermore, Hebrews 4:14-16 illustrates that Jesus empathizes with our weaknesses and intercedes for us, showcasing his divine nature and authority. Moreover, the concept of Jesus' priesthood is further elaborated in Hebrews 7:14-16, where it is stated that Jesus' priesthood is based on the power of an indestructible life, contrasting with the temporary nature of earthly priests. This highlights that Jesus' sacrifice was once for all, as he offered himself without the need for repeated sacrifices, which is a key aspect of his role as the eternal High Priest. Additionally, the Gospels affirm that Jesus voluntarily laid down his life for humanity. In Mark 10:45, Jesus states that he came to serve and give his life as a ransom for many, reinforcing the idea that his sacrifice was intentional and part of God's redemptive plan. John 10:14-18 further emphasizes this point, as Jesus claims authority over his life and death, indicating that his sacrifice was not only necessary but also a fulfillment of divine purpose.
