How should Christians respond to the false teaching of works-based salvation?

In the face of false teachings advocating works-based salvation, Christians are called to uphold the truth that salvation is by grace alone through faith alone in Christ alone. The Apostle Paul rebukes those who would add any works to the Gospel, illustrating that attempting to gain God's favor through our efforts is both futile and contrary to the essence of the Gospel (Galatians 6:12-13). This means believers must remain steadfast in the message of grace, recognizing that their acceptance before God is based solely on Christ's righteousness rather than their own. The proper response includes not only personal belief but also a commitment to warn others of such heresies and to defend the true Gospel to protect their communities from error.
