Why is substitutionary atonement important for Christians?

The significance of substitutionary atonement lies in its demonstration of God's justice and mercy in perfect harmony. Christ had to bear the sins of His people to satisfy divine justice, as outlined in the sermon. As stated, Christ 'became us' and was made to be sin so that we might be justified before God. This theological concept not only assures us of our standing before a holy God but also emphasizes the depth of Christ's sacrificial love. Without substitutionary atonement, the concept of forgiveness would lack a solid foundation, leaving humanity without hope for redemption.
