It is unjust for God to punish Jesus for the sins of others, and it is more merciful for God to forgive sin without requiring a blood sacrifice.

Muslims often argue that the idea of one person suffering for the sins of another is unjust, citing the Qur'an's teachings against vicarious punishment. However, Christians understand that Jesus' death was not an act of injustice but rather a profound act of love and sacrifice. The New Testament emphasizes that Jesus, being sinless, voluntarily took on the sins of humanity to fulfill God's plan for redemption. This act was necessary to satisfy divine justice while simultaneously demonstrating God's mercy. Furthermore, the Qur'an itself contains narratives that suggest the concept of substitutionary sacrifice, such as the story of Abraham and the ram provided by God as a substitute for his son, which aligns with the Christian understanding of atonement. Thus, the Christian perspective sees Jesus' sacrifice as the ultimate fulfillment of God's justice and mercy, rather than a contradiction of it.
