What does the Bible say about being saved by grace alone?

Ephesians 2:8-9 emphasizes that we are saved by grace through faith, not by works, lest anyone should boast. This grace is offered to sinners through the redemption found in Christ alone, who implies that righteousness cannot come through the law. Galatians 2:21 states that if righteousness could come through the law, then Christ died for no purpose. Therefore, the central theme of Scripture underscores the necessity of grace for salvation, as seen in Romans 3:24, 'and are justified freely by his grace through the redemption that came by Christ Jesus.' In historic Reformed theology, grace alone is the foundation of our faith and the means by which we are made acceptable to God.
