2 Corinthians 9:14

while they themselves also, with supplication on your behalf, long after you by reason of the exceeding grace of God in you. [This ministry of yours, in giving to the poor at Jerusalem, not only fills up the measure of the wants of these people of God, but overflows that measure, for it results in many thanksgivings to God. And these results are evident, for by thus showing your liberality to the Jewish church at Jerusalem, you prove to it that you are indeed true and obedient to your confession of your faith in the gospel of Christ, and thus cause them to glorify God, as they also do for the liberality of your contribution unto them and (potentially) unto all. You cause them also to pray for you and long to see you face to face, that they may know those in whom God's grace abounds to so full a measure. It will be remembered that the church in Jerusalem, influenced by the prejudices of the Jews which surrounded it, and also by the sentiments and feelings which it inherited from its previous life, looked upon the church as planted by Paul, with eyes full of suspicion. They regarded these churches as lawless bodies, inimical to all that the Jews held as ancient or sacred. They were ready to believe any wild rumor which might start with regard to the unchristian character of the apostle's converts, and the reckless lawlessness of the apostle himself. The riot which arose soon after when Paul was found in the temple at Jerusalem aptly illustrates the attitude of the Jewish mind toward him and his work. Now the apostle felt confident that a liberal gift from his Gentile churches would bring about a better understanding, and would work wonderful changes in the thoughts of Jewish Christians. He felt that it would persuade the latter that his Gentile converts were truly obedient to the religion which they confessed, and that it would persuade them also that those who had overcome their prejudices sufficiently to give liberally to Jews would have no prejudices which would prevent them from giving liberally to other people. He was likewise confident that the Jewish Christians, seeing these things, would be fully persuaded of the genuine Christian grace of his converts, and therefore would not only pray for them, but even long for personal acquaintance and fellowship with them. How far the apostle was correct in this judgment we can not say; but he certainly seems to have been well received by the Christians at Jerusalem when he came as the representative of these Gentile churches. If the attitude of the unchristian Jewish mind toward him was still relentlessly bitter, it must be borne in mind that he took no collection for them, and that they were in no manner in his thought in this connection.]
