Further Reasons Why They Should Reveal Their Generosity (2 Corinthians 9:1-15).
It is often noted that this chapter appears to repeat to some extent the ideas in chapter 8, yet from a different angle, and seems to begin almost from scratch. And this has caused some to think that this is a separate letter. But this is not only unnecessary and not supported by any manuscript evidence, but ignores the niceties of his situation.
He has finished off chapter 8 with a reference to his ‘glorying' on their behalf, something which in fact is not otherwise mentioned in chapter 8 but is clearly explained in chapter 9, and the mention of ‘the brothers' in chapter 9 assumes their introduction in chapter 8. In fact, his very mentioning of his glorying on their behalf may well be precisely what pulled him up short and made him realise that he had up to this point been less than tactful. We might see him as realising that here were the Corinthians, with whom he had just recently been reconciled, who had been the first to take a real interest in the Collection (1 Corinthians 16:1), having newcomers to the idea thrust in their face as an example, and lauded to the skies, while they could argue that it was they who should be held up as an example.
It was true that on him the eager self-sacrifice of the Macedonians had made a great impression, but he probably suddenly recognised that it might not be seen in the same light by the touchy Corinthians. Indeed their pride might well be hurt. Thus 2 Corinthians 9:1 sees him hurriedly trying to assure them that in fact he does recognise that what he has said might seem a little superfluous in the light of the fact that they have already proved their readiness, and goes on to stress that in reality they had been the example that he had used to spur others on to take up the idea of the Collection with enthusiasm.
Thus his point about the self-sacrifice of the Macedonians might now, he hoped, be taken for what it was, an example of sacrificial giving, but not as a suggestion of their having failed. There may even be a case for suggesting that he had had a break in his letter writing which had made him recognise how tactless he had been, so that on again taking up his pen he sought to put matters right. (Such bursts of realisation often come out of the blue when least expected).
