Why is the atonement of Christ vital for salvation?

The significance of Christ's atonement lies in its purpose and scope. He endured the full wrath of God for the sins of His people, thus satisfying divine justice. As Mike McInnis emphasizes in the sermon, Christ was 'lifted up' to draw men to Himself, yet this drawing is specific to those whom the Father has chosen. This reflects the nature of God's saving work; it is selective and rooted in sovereign grace. Throughout the Old and New Testaments, the atonement is depicted as a fulfillment of God's promise to His chosen people, ensuring that those who are called will experience redemption and grace. The reality of Christ’s suffering illustrates the depths of God's love and justice, making the atonement foundational for any understanding of salvation.
