To frustrate the grace of God means to regard it as unnecessary and to attempt to achieve salvation through one's own works (Galatians 2:21).
Frustrating the grace of God involves attempting to add human merit or works to the grace offered through Jesus Christ. In Galatians 2:21, the Apostle Paul asserts that doing so effectively makes the grace of God void and disregards its essential role in salvation. This corruption of the gospel distorts the purpose of grace and sends the message that Christ's sacrificial work was insufficient, directly contradicting the core message of the New Testament that emphasizes salvation by grace alone, through faith alone. A proper understanding of grace leads believers to completely rely on Christ for their salvation and to understand that they cannot contribute to it in any way.
