Even at the close Paul cannot refrain from personal references. He points to his example of absolute disinterestedness, and with a dramatic gesture holds out 'these hands' to show how they are hardened by work. Such a warning against doing God's work for money would not have been his last word, at a time when all hearts were strung up to the highest pitch, unless the danger had been very real. And it is very real to-day. If once the suspicion of being influenced by greed of gain attaches to a Christian worker, his power ebbs away, and his words lose weight and impetus.
It is that danger which Paul is thinking of when he tells the elders that by 'labouring' they 'ought to support the weak'; for by _weak_ he means not the poor, but those imperfect disciples who might be repelled or made to stumble by the sight of greed in an elder. Shepherds who obviously cared more for wool than for the sheep have done as much harm as 'grievous wolves.'
Paul quotes an else unrecorded saying of Christ's which, like a sovereign's seal, confirms the subject's words. It gathers into a sentence the very essence of Christian morality. It reveals the inmost secret of the blessedness of the giving God. It is foolishness and paradox to the self-centred life of nature. It is blessedly true in the experience of all who, having received the 'unspeakable gift,' have thereby been enfranchised into the loftier life in which self is dead, and to which it is delight, kindred with God's own blessedness, to impart.
