This, says Paul, was his case. "Though I preach the Gospel, I have nothing to glory of: for necessity is laid upon me; yea, woe is unto me, if I preach not the Gospel!" His call to the ministry had been so exceptional, and had so distinctly and emphatically declared the grace and purpose of Christ, that he felt bound by all that can constrain a man to the devotedness of a lifetime. Paul felt what we now so clearly see: that on him lay the gravest responsibilities. Had he declined to preach, had he complained of bad usage, and stipulated for higher terms, and withdrawn from the active propagation of Christianity, who would or could have taken up the task he laid down? But while Paul could not but be conscious of his importance to the cause of Christ, he would arrogate to himself no credit on account of his arduous toil, for from this, he says, he could not escape; necessity was laid upon him. Whether he does his work willingly or unwillingly, still he must do it. He dare not flinch. If he does it willingly, he has a reward; if he does it unwillingly, still he is entrusted with a stewardship he dare not neglect. What then is the reward he has, giving himself, as he certainly does, _willingly_ to the work? His reward is that "when he preaches the Gospel he makes the Gospel of Christ without charge." The deep satisfaction he felt in dissociating the Gospel of self-sacrifice from every thought of money or remuneration and in offering it freely to the poorest as his Master's fit representative was sufficient reward for him and incalculably greater than any other he ever got or could conceive. In other words, Paul saw that however it might be with other men, with him there was no alternative but to preach the Gospel; the only alternative was--was he to do it as a slave entrusted with a stewardship, and who was compelled, however reluctant he might be, to be faithful, or was he to do it as a free man, with his whole will and heart? The reluctant slave could expect no reward; he was but fulfilling an obligatory, inevitable duty. The free man might, however, expect a reward; and the reward Paul chose was that he should have none--none in the ordinary sense, but really the deepest and most abiding of all: the satisfaction of knowing that, having freely received, he had freely given, and had lifted the Gospel into a region quite undimmed by the suspicion of self-seeking or any mists of worldliness.
