Why is Christ referred to as the author and finisher of our faith?

Christ's role as the author and finisher of our faith encapsulates the entirety of the redemption process. As the author, He designed and promised salvation even before creation, as affirmed in Ephesians 1:4. His redemptive work is not just about initiating faith; it extends to its completion, ensuring that all whom He calls are ultimately saved. This reflects the sovereignty of His grace in all aspects of our salvation, from being chosen in Him to the finality of our redemption through His sacrifice on the cross. Thus, believers can rest in the assurance that their faith is secure in Christ’s finished work.
