How do we know that Christ's work of redemption is secure?

The security of Christ's redemptive work is rooted in His nature as the successful Savior. In the sermon, it is emphasized that everything Christ set out to accomplish came to pass, highlighting His sovereignty and authority. He operates under the authority of God the Father and fulfills the redemptive plan laid out since the foundation of the world. Scripture affirms that He has come to seek and save the lost, and nothing can thwart His plans. Thus, believers can have total assurance in the sufficiency and effectiveness of Christ's atonement and His ability to bring about the salvation of His people.
