How do we know that Christ's death justifies us?

Our justification through Christ's death is affirmed by His resurrection, as seen in Romans 4:25, which states, "Who was delivered for our offenses, and was raised again for our justification." This means that God accepted the sacrifice of Christ for our sins, and His resurrection is the evidence that our justification is complete. The resurrection indicates that the debt of sin has been fully paid and that God's justice has been satisfied. Therefore, for believers, Christ's resurrection is not merely a historical event but the linchpin of our assurance that we are justified before God.
