What role does Christ play in fulfilling the law for believers?

In fulfilling the law, Jesus Christ stands as the only one who has fully obeyed its requirements (Matthew 5:17). As described in Romans 8:3-4, 'For what the law could not do, in that it was weak through the flesh, God sending His own Son in the likeness of sinful flesh, and for sin, condemned sin in the flesh.' By His obedience and sacrificial death, Christ provides a perfect righteousness for believers. This righteousness is credited to them through faith (Philippians 3:9), establishing that salvation is not based on human effort but on the grace provided through Christ. Thus, believers can stand before God justified, as Christ’s fulfillment of the law is counted as theirs.
