In his sermon, Gordie Hunt addresses four pivotal questions about being justified by faith alone, as discussed in Galatians 2:16-19. He explores the foundation of justification, emphasizing that it is not through the law but through faith in Jesus Christ. Gordie clarifies that our deeds do not secure our righteousness; instead, faith in Christ's sacrifice assures our standing before God. He challenges listeners to embrace this truth without reverting to legalistic beliefs by reiterating the theme of being justified by faith alone.
