What does the Bible say about the finished work of Christ?

The finished work of Christ refers to His complete obedience to the will of the Father, culminating in His sacrificial death and resurrection. In John 4:34, Jesus states, 'My meat is to do the will of Him that sent me, and to finish His work.' This highlights that salvation is not based on human effort but solely on Christ’s fulfillment of the law and His righteousness. His work redeems sinners by establishing a perfect righteousness necessary for acceptance with God, fulfilling the promises prophesied in the Old Testament.

Moreover, the New Testament confirms that Jesus is both the author and perfecter of faith (Hebrews 12:2), indicating that the entire scope of salvation—from election in the Father to redemption by the Son and application by the Holy Spirit—is accomplished through His finished work. Thus, the importance of His completed work is foundational to the doctrines of sovereign grace, reminding believers that salvation is entirely a gift from God.
