What makes salvation so great according to the Bible?

Hebrews reveals that what makes salvation great includes several key factors: the author, Jesus Christ, is God Himself, highlighting its divine origin. Moreover, the eternal power inherent in this salvation means it cannot be undone. The wisdom of God's plan justifies sinners while maintaining His justice. Additionally, the immense cost is demonstrated through the shedding of Christ’s blood, reflecting its profound value. Finally, the success of salvation is evident, as Christ accomplished His mission to bear our sins and fully satisfy God's requirements, completing the work necessary for our redemption.
