How do we know Christ is the author of our salvation?

The concept of Christ as the author of our salvation is clearly articulated in Hebrews 5:9, which points to His obedience and completion of the work assigned to Him. Christ's role as the originator of salvation underscores that it is through Him that eternal life is granted. Before time began, God established a covenant of grace, ensuring that salvation would be fulfilled through His Son's life, death, and resurrection. By executing this divine plan, Christ not only secured salvation for those He came to save but also affirmed His unique position as the sole mediator between God and man. His perfect obedience makes Him the only adequate source of salvation, further substantiating the claims of Scripture regarding His divine authority in the matter.
