What does it mean that Jesus is the author of salvation?

When we refer to Jesus as the author of salvation, we acknowledge Him as the one who not only begins the work of redemption but also completes it. This is emphasized in Hebrews 5:9, where salvation is portrayed as a finished work, accomplished through His obedience and sacrifice. The idea of 'author' implies creative power and authority; thus, Jesus orchestrates every detail of salvation according to His divine plan. This also means that any attempt to add human works to the equation of salvation undermines the sufficiency of Christ’s atoning work. The assurance of salvation rests in the finished work of Christ, who stands as the supreme high priest, having mediated an eternal covenant for His people.
