The apostle Paul had proclaimed the Gospel to the Galatians and they received it. However, since then false teachers have infiltrated their churches and are deceiving the Galatians with another so called gospel. Paul hears of this and he is astonished. His message to the Galatians is clear. There is only one Gospel and that Gospel teaches: you can only be justified before God by faith alone through grace alone in Christ alone to the glory of God alone. Therefore, embrace the Gospel and walk in the freedom it gives.
