How do we know Jesus's sacrifice on the cross was sufficient?

The sufficiency of Christ's sacrifice rests on several key truths found in Scripture. First, Romans 8:1 declares, 'There is therefore now no condemnation to them which are in Christ Jesus.' This declaration emphasizes that Christ's death on the cross fully paid the penalty for sin, thus satisfying divine justice. Additionally, in Romans 10:4, Paul writes that 'Christ is the end of the law for righteousness.' This means that Jesus’s perfect obedience and sacrificial death meet the law's demands in full, granting righteousness to all who believe. Therefore, through His death, justice is not only satisfied but also gifts us a standing before God that is free from condemnation.
