Why is it important to understand that Christ didn't die for everyone?

The sovereignty of God in salvation is a core tenet of Reformed theology, which posits that Christ's atoning work was specifically for His chosen people, not indiscriminately for all humanity. This is crucial because it removes uncertainty from salvation; all for whom Christ died will undoubtedly be saved. Understanding this truth reflects the deep love of God, demonstrating that His justice and mercy coalesce perfectly in the election of His people. It also serves as a protection against the false gospel that suggests salvation is conditioned upon human effort or decision.
