1 Corinthians 12:3 - Joseph Benson’s Commentary on the Old and New Testaments

Wherefore Since it was so with you once, and it is otherwise now, this is a full demonstration of the truth of the Christian religion, through your faith in, and reception of, which, you received these gifts, which none of the heathen idols, blind, and dumb, and lifeless as they were, could possibly confer upon you. I give you to understand, that no man, speaking by the Spirit of God Who is endued with these spiritual gifts, or is at all inspired by the Holy Spirit; calleth Jesus accursed Pronounces him to be an impostor, and therefore justly punished with death. It seems that some, who pretended to be inspired, did this; probably the Jewish exorcists, together with the heathen priests and priestesses, who in their enthusiastic fits reviled Jesus. Now the apostle intended here to teach the Corinthians, that if any such persons were really inspired, that is, if they spake by any supernatural impulse, it certainly proceeded from evil spirits, and not from the Spirit of God, who never would move any one to speak in that manner of Jesus. By this the apostle cuts off all who spoke blasphemously and irreverently of Christ, whether Jews or heathen, from all pretences to the possession of spiritual gifts, or of any supernatural influence from the true God. These gifts and inspirations could only be found among true Christians. On the other hand, no man can say that Jesus is the Lord Can receive him as such; can think or speak reverently of him; can make profession of his name, when that profession would expose him to imprisonment and martyrdom; can worship him aright, and heartily acknowledge his divinity and lordship, (against which there was then the greatest opposition made,) so as to subject himself sincerely and entirely to his government: but by the Holy Ghost By his directing, renewing, and purifying influences. The sum is, None have the Holy Spirit but true Christians; true believers in, and disciples of, the Lord Jesus; and all such have the Spirit, at least in his enlightening and sanctifying graces.
