Why is understanding the fulfillment of the law in Christ important?

Understanding that the law is fulfilled in Christ is vital to Reformed theology. The law, while good and true, was never intended to secure our salvation. Instead, it serves to reveal our inability to meet its demands. Christ embodies the law and fulfills its requirements through His life, death, and resurrection. By embracing Him, believers receive the righteousness that the law requires but that we cannot achieve on our own. This truth liberates us from the burden of legalism and leads us to a relationship with God grounded in grace rather than performance. Knowing this foundation allows Christians to grow in maturity—moving from basic principles to a deeper understanding of the gospel, ultimately allowing us to discern good from evil through the lens of Christ.
