In Acts 15:1-11, the early church is forced to confront a dangerous distortion of the gospel when certain Jewish believers begin teaching that salvation requires both faith in Jesus and obedience to the Mosaic law. Paul, Barnabas, and Peter fiercely defend the truth that sinners are justified by grace alone through faith alone in Christ alone. The passage reminds us that the gospel is worth fighting for because adding human effort to salvation ultimately devalues the sufficiency of Christ’s finished work on the cross. At the heart of the Jerusalem Council is the glorious truth that both Jew and Gentile are saved the exact same way: entirely by the grace of the Lord Jesus.
