Why is the atonement of Christ significant for Christians?

The atonement of Christ is fundamental to Christian faith as it represents the means by which God's justice is satisfied while His mercy is extended to the elect. Hebrews 9:22 asserts that without the shedding of blood, there is no remission of sins, highlighting the necessity of a sacrificial system fulfilled in Christ’s sacrifice. This act not only reconciles believers to God (Romans 5:10) but also illustrates the depth of His love and commitment to save His people from their sins (Matthew 1:21). Moreover, through His atonement, Christ satisfies divine justice, allowing God to forgive sins without compromising His holiness, thus showcasing the glorious intersection of justice and mercy within the narrative of redemptive history.
