Some believed. Luke declareth that this was at length the success of the disputation, that they did not all profit [1] in the same doctrine. We know that the apostle was endued with such grace of the Spirit, that he ought to have moved stones; and yet he could not, after long disputing and testifying, win all men unto Christ. Wherefore, let us not marvel, if the unbelief of many do at this day resist the plain doctrine of the gospel, and if many remain obstinate, to whom the truth of Christ is no less made manifest than the sun at noon-day. Moreover, those return from Paul blind and blockish, who came unto him willingly, as if they had been desirous to learn. If there were such stubbornness in voluntary hearers, what marvel is it if those refuse Christ with a malicious [2] mind, who swell with pride and malice, [bitterness] and do openly fly and hate the light?

Some believed, etc. - His message was there treated as his Gospel is to the present day: some believe, and are converted; others continue in obstinate unbelief, and perish. Could the Jews then have credited the spiritual nature of the Messiah's kingdom, they would have found little difficulty to receive Jesus Christ as the Messiah.
Multitudes of those now called Christians can more easily credit Jesus as the Messiah than believe the spiritual nature of his kingdom. The cross is the great stumbling block: millions expect Jesus and his kingdom who cannot be persuaded that the cross is the way to the crown.

(13) And some believed the things which were spoken, and some believed not.
(13) The Gospel is a taste of life to those that believe, and a taste of death to those that are disobedient.

And some believed the things which were spoken,.... By him, concerning the kingdom of God and Jesus Christ; even as many as were ordained unto eternal life, and to whom it was given to believe; for faith is the gift of God, and which comes by hearing of the word, when it is attended with a divine power; and then it is not only notionally understood, and barely assented to as truth, but is cordially believed and embraced, and cheerfully professed, and steadily held fast: this was not a mere historical faith, or a bare assent to the truth of the things spoken, nor a mere profession of faith in them, but a believing in Christ with the heart, the sum and substance of them; as they heard these things, their understandings were enlightened, and they saw their need of Christ, and the things of Christ, which were held forth in the ministry of the word; and so approved of them, savoured, relished, and fed upon them; and until this is the case, none can, nor will believe aright:
and some believed not: notwithstanding the full proof, and clear evidence produced by the apostle: these were not of Christ's sheep, their eyes were blinded, and their hearts were hardened, as was prophesied of them, and therefore they could not believe; they were given up to a judicial blindness and hardness of heart, and were left under the power of obstinate and invincible unbelief: their disbelief of these things arose from the prejudices they had conceived about a worldly kingdom; from the sufferings and death of Jesus Christ, they imagining the Messiah would not die, but abide for ever; from the carnal reasonings of their minds, about divine and spiritual things; and from the ignorance that was in them, because of the obduracy of their hearts. The kingdom the apostle testified of was not an Utopian kingdom, nor any of the real kingdoms of this world, but the kingdom of the Messiah they were expecting; but that which he described, being not such an one as they imagined, they believed him not: the things he said concerning Jesus were not trivial, speculative, and indifferent things; but of the greatest moment and importance, and of which there was full proof in their own writings; and though spoken by Paul, were no other than the word of God; and besides, were good news, and glad tidings, and yet they believed them not: this difference among them, some believing and some not believing, was not owing to the power and free will of man, as if some of themselves would, and did believe, and others would not, but to the distinguishing grace of God; for faith is not of man, it is the gift of God, it is the fruit of electing grace, and is given in consequence of it: nor is this any unusual thing, under the same ministration of the word, for one to believe, and another not believe: this is a common case, and is the usual success the Gospel meets with; so it always has been, and so it is, and will be; so it was in the times of Noah, he was a preacher of righteousness to the old world, even of the righteousness of faith, many were disobedient, few believed; and so it fared with the evangelical prophet Isaiah, and with Jeremiah, Ezekiel, Zechariah, and other prophets of the Old Testament; and with John the Baptist, the forerunner of Christ, and with Christ himself, as well as with our apostle; and this has been the case ever since his time, now is, and will be, as long as the Gospel is preached.

and some believed . . . some not--What simplicity and candor are in this record of a result repeated from age to age where the Gospel is presented to a promiscuous assemblage of sincere and earnest inquirers after truth, frivolous worldlings, and prejudiced bigots!

And some believed the things that were spoken - With the heart, as well as understanding.
