How do we know that trusting Christ is the essence of obedience?

The true essence of the law and our obedience lies not in our successful adherence to its commands, but in our reliance on Christ's perfect obedience. As highlighted in the sermon, any attempt to earn righteousness through our own works amounts to a covenant of works, which ultimately can only lead to failure and condemnation. Our assurance comes from knowing that Jesus fulfilled the law completely and made the ultimate sacrifice for our sins. This highlights the principle that salvation is by grace through faith, ensuring that our obedience is a response to His grace rather than a means of achieving it. By trusting in Christ as our sole righteousness, obedience becomes a natural outcome of our faith rather than an effort to earn favor.
