<p>9:14 <i>While they also, with prayers on your behalf, long after you by reason of the exceeding grace of God in you</i>- I noted earlier that Paul had exaggerated about the Corinthians supposedly longing for Titus and himself. And he makes a similar exaggeration here. The Jerusalem Christians likely had little knowledge of the Corinthians, and so the language of longing and praying is exaggeration. It was Paul who uses the word &quot;long after you&quot; several times about his longing after his brethren; and he imagines that the Corinthians have the same attitude to their brethren as he does. The grace (gift) &quot;in you&quot; is a reference to the gift of the Holy Spirit in the hearts of the Corinthians, within them, which Paul has so often alluded to in his Corinthian correspondence. He urges the Corinthians to make use of that gift, to allow the path of the Spirit, which would elicit in them a giving of grace to others. But it is questionable whether in reality the Jerusalem Jewish Christians longed for the Corinthians upon that basis. But in theory, yes- the &quot;fellowship of the Spirit&quot; was and is a fellowship experienced on the basis of each believer having the Spirit at work in their hearts, and responding to it. This creates a fellowship with others who are allowing the same process.</p>
