Why is Christ's work on the cross significant for salvation?

The significance of Christ's work on the cross lies in its ability to reconcile sinful humanity with a holy God. As stated throughout 1 Peter, particularly in discussions of Christ taking on our sin and bearing it away, the sacrifice serves as the ultimate atonement. By fulfilling the requirements of divine justice, Christ removes the barriers that once stood between man and God. Thus, for believers, Christ’s finished work is foundational; it grants us the ability to confidently approach God's throne of grace, as justice has been satisfied through Christ's blood. This assurance transforms our relationship with God, aligning it with His righteousness and mercy.
