How do we know that good works are not the evidence of salvation?

In the discourse, it is emphasized that good works cannot be the root or evidence of salvation. As articulated in Romans 3:28, we are justified by faith without the deeds of the law. This means that salvation is a gracious gift, not dependent on our actions or moral deeds. The true evidence of salvation is a change in heart, where faith leads us to trust wholly in Christ's sufficiency rather than our own merits. When believers recognize that their righteousness is derived from Christ alone, they display a new desire to live in a manner that honors God, not because it earns salvation but because it flows from love for the Savior.
