What does Galatians 5:8 say about the persuasion to turn away from grace?

Galatians 5:8 declares that the persuasion to turn away from grace does not come from the One who calls you. Since the Holy Spirit called them, this persuasion is not of the Holy Spirit; it is of the evil spirit. Only two spirits exist: the Holy Spirit or the satanic evil spirit.

Les explains that Paul had indoctrinated and taught the Galatians, yet someone was blowing them away. Paul asks who hindered them from obeying the truth, and he knew it was the Judaizers. Les teaches that verse 8 says this persuasion to come away from Paul's Gospel of Grace “cometh not of him who calleth you.” The One who called them is the Holy Spirit. If the Holy Spirit did not lead them away, then the evil spirit did, because there are only two spirits in the world: the Holy Spirit or the satanic evil spirit. Les also uses the illustration of a person in a heavily programmed area, asking who fooled with you, to show how surprising it is when someone is different.

Galatians 5:8

This persuasion cometh not of him that calleth you.

Where did the persuasion to go back under legalism come from according to Galatians 5:8?

According to Galatians 5:8, the persuasion to return to legalism did not come from the One who calls you—the Holy Spirit who brought them out of paganism. Instead, it came from the same evil spirit that had held them in paganism until the Gospel freed them.
