Christ's sacrifice refers to the belief in Christianity that Jesus Christ willingly gave his life to atone for the sins of humanity. This act is seen as a demonstration of God's love and mercy, providing a path for reconciliation between God and people. The crucifixion, where Jesus was nailed to a cross, is central to this belief, symbolizing the ultimate sacrifice. The significance of Christ's sacrifice is celebrated during Holy Week, particularly on Good Friday, when Christians remember the crucifixion. It is believed that through his death and subsequent resurrection, Jesus conquered sin and death, offering eternal life to those who believe in him.
