What does the Bible say about the Galatians being bewitched?

In Galatians 3:1, the Apostle Paul expresses his astonishment that the Galatians have been bewitched, meaning they were deceived or charmed into abandoning the pure gospel of grace for a gospel that includes works. The false prophets flattered the Galatians by telling them that while salvation is by grace, they must also follow the law, such as the practice of circumcision. This misguided belief directly contradicts the message of grace and the sufficiency of Christ's finished work on the cross.
