Jesus' sacrifice is deemed successful because He declared 'It is finished,' signifying the complete atonement for sin (John 19:30).
The success of Jesus' sacrifice is not based on subjective interpretations but on the definitive claim of Scripture. When Christ proclaimed 'It is finished' at Calvary, He affirmed that every requirement of divine justice had been satisfied. His death effectively reconciled the elect to God, ensuring that all whom the Father has given Him are saved. The resurrection serves as the divine validation of His successful atonement, demonstrating that God accepted His sacrifice as sufficient to atone for the sins of His people. Therefore, believers can rest assured that their salvation is fully accomplished in Christ.
