Jesus is called the author of salvation because He alone accomplishes the work of salvation for all His people.
In Hebrews 5:9, Jesus is described as the author of eternal salvation, which underscores His unique role as the sole initiator and accomplisher of salvation. This is significant because it clarifies that no one contributes to this work; salvation is entirely the product of His grace and mercy. Scripture emphasizes that God is both the just and the justifier, meaning that Jesus fulfills the requirements of justice while also providing redemption for sinners. His sacrificial death on the cross serves as the final and sufficient payment for sin, hence the term 'author' reflects His preeminent authority and divine agency in the deliverance of His people.
