Charles Spurgeon Commentary Acts 13:38-42

"Be it known unto you therefore, brethren, that through this man is proclaimed unto you remission of sins: and by him every one that believeth is justified from all things, from which ye could not be justified by the law of Moses. Beware therefore, lest that come upon [you] which is spoken in the prophets: Behold, ye despisers, and wonder, and perish; For I work a work in your days, A work which ye shall in no wise believe, if one declare it unto you. And as they went out, they besought that these words might be spoken to them the next sabbath." — Acts 13:38-42 (ASV)

Be it known unto you therefore, men and brethren, that through this man is preached unto you the forgiveness of sins: and by him all that believe are justified from all things, from which you could not be justified by the law of Moses. Beware therefore, lest that come upon you, which is spoken of in the prophets; Behold, you despisers, and wonder, and perish: for I work a work in your days, a work which you shall in no wise believe, though a man declare it unto you. And when the Jews were gone out of the synagogue, the Gentiles besought that these words might be preached to them the next Sabbath.

They did not mind hearing sermons twice in those days. We are not often asked to preach the same sermon over again. But these people wanted to know the truth; and, therefore, they asked to have it repeated. If our people will not receive the gospel the first time we preach it, we must tell it to them over and over again. With the hammer of the Word, we must strike the same nail on the head again and again. Even if we do not utter the same words, there must always be the same subject Sabbath by Sabbath, and week by week.
