Why is Christ's active and passive obedience important for salvation?

The distinction between Christ's active and passive obedience is crucial in Reformed theology. His active obedience refers to His perfect law-keeping throughout His life, while His passive obedience pertains to His willing suffering and death on the cross for our sins. As stated, 'I'm saved by His active obedience, His law-keeping. I'm saved by His passive obedience when He became obedient unto death, even the death of the cross' (Todd Nibert). This dual nature of Christ's obedience ensures that He not only fulfills the requirements of the law but also satisfies God's justice by bearing the penalty for sin. Without understanding both aspects, we miss the completeness of the gospel message that offers true hope and salvation.
