How do we know that Christ's sacrifice is sufficient for our reconciliation?

The sufficiency of Christ's sacrifice lies in the dual witness of His death and resurrection. Romans 4:25 teaches that Christ was raised for our justification, signifying that God accepted His sacrifice as a full payment for our sins. This resurrection serves as a visible assurance to believers that the price required for sin has been fully met. Furthermore, Christ's ascension into heaven and intercession on behalf of believers underscores His continual role as our mediator, ensuring that the reconciliation initiated on the cross is both effective and enduring. Thus, the resurrection not only confirms the accomplishment of Christ’s sacrifice but also assures us that those who trust in Him are fully reconciled to God.
