Matthew Poole and continuators on Galatians 3:2

2 This only would I learn of you, Received ye the spirit , by the works of the law, or by the hearing of faith ?

By the Spirit here is understood the gifts of the Spirit, which were either such as were common to all believers, (such as Faith, Love, &c.) or else such as were peculiar to some, and those not all Believers; such were those abilities for miraculous operations given to some. Some understand this Text of the former, some of the latter; It's best to take in both; all the manifestations of the Spirit then given out, either for the Sanctification and Eternal Salvation of those to whom they were given, or for the confirmation of the Truth of the Gospel.

Did you receive the Spirit by the works of the Law, that he knew they could not say they did; for they were Heathens; strangers to the Commonwealth of Israel, so as they could pretend to no works of the Law: Did you receive this Holy Spirit upon hearing the Gospel, (which is the Doctrine of Faith) preached to you: Men should take heed of villifying that Ministry, or that Doctrine, which God hath blessed to the change of their own hearts, or the hearts of others: We also may observe from hence, That the hearing the Gospel faithfully preached is a blessed means by which mens hearts are changed, and they receive the Holy Spirit: not inabling them, (as it did some and but some in the beginning of the Gospel,) to work signs and wonders, but inabling them to the operations of a Spiritual Life: The strength of the Apostles argument is this, you have the greatest reason to own that Doctrine as the truth which God hath blessed to your Souls to produce Spiritual Effects there.
