Why is trusting Christ alone important for salvation?

The sermon emphasizes that salvation is solely through Christ’s righteousness, not ours. Isaiah 57 speaks of the futility of seeking righteousness through works, which ultimately leads to despair. Our attempts, symbolized by offerings and sacrifices, are not what God desires; rather, He requires faith in His Son. Romans 3 confirms this, stating that righteousness is imputed to those who believe, not based on their works. Thus, trusting Christ alone for salvation underscores the reality that He has fulfilled the law on our behalf, making our faith necessary for receiving His grace.
