Galatians 5:8

This persuasion - Of the necessity of your being circumcised and obeying the law of Moses, is not of him that calleth you. I never preached such a doctrine to you; I called you out of bondage to liberty, from a galling yoke to a cheerful service. Some translate πεισμονη, obedience or subjection. This subjection of yours to the Mosaic law is opposed to the will of God, and never was preached by me.

This persuasion - This belief that it is necessary to obey the laws of Moses, and to intermingle the observance of Jewish rites with the belief of the Christian doctrines in order to be saved.

Not of him that calleth you - That is, of God, who had called them into his kingdom. That it refers to God and not to Paul is plain. They knew well enough that Paul had not persuaded them to it, and it was important now to show them that it could not be traced to God, though they who taught it pretended to be commissioned by him.

5:8 This your present persuasion cometh not from God, who called you - to his kingdom and glory.
