Why is fulfillment of the law by Christ important for Christians?

Jesus did not come to abolish the law but to fulfill it (Matthew 5:17). His perfect obedience and sacrificial death satisfied the demands of the law and paid the penalty for sin on behalf of His people. This act of fulfilling the law is crucial, as it enables believers to be credited with the righteousness of God through faith in Christ (2 Corinthians 5:21). Consequently, Christians can stand before God without condemnation, as they are seen through the lens of Christ's righteousness, ultimately giving them assurance of salvation and access to eternal life.
