Why is the understanding of salvation through grace important for Christians?

The doctrine of salvation by grace highlights the fundamental Reformed belief that humanity cannot achieve righteousness through works of the law. This understanding is critical for Christians because it shifts the focus from personal merit to Christ's finished work. In the sermon, it is noted that a reliance on one's works leads to blindness regarding true righteousness revealed in Jesus. Recognizing salvation as a gift of grace ensures humility and faithfulness in discipleship, where believers understand that they are justified and maintained in their faith solely by the grace of God, encapsulated succinctly in Ephesians 2:8-9.
