But our faith makes us abundant in good works. May I say to you, if you are doing all you possibly can for Christ, endeavour to do yet more? I believe a Christian man is generally right when he is doing more than he can; and when he goes still further beyond that point, he will be even more nearly right. There are scarcely any bounds to the possibilities of our service. Many a man, who now is doing little, might, with the same exertion, do twice as much by wise arrangement and courageous enterprise.
Charles Spurgeon, An All-Round Ministry, p. 22
