How do we know that Christ's work is effective for salvation?

The sermon emphasizes that Christ's work is thoroughly effective for salvation, as demonstrated by His proclamation on the cross, 'It is finished.' This declaration signifies the completion of the work necessary for the redemption of His people. Additionally, the resurrection of Christ serves as a powerful affirmation of His success in securing salvation. The transformed lives of believers, who are drawn to God and made honorable through faith, illustrate the ongoing impact of Christ's work. Thus, the evidence of Christ's redemptive mission is seen not only historically but also experientially in the lives of those He saves.
