A more frequent cause, however, of weak hands and feeble knees, is starvation, absolute starvation. Is there such a thing known in England as starvation? Yes, there is of a spiritual kind. There are many houses which are dedicated to the worship of God, that certainly never were dedicated to the profit of man. There are places into which a Christian might enter all the year round, without ever getting any understanding of the doctrines of God at all. Many a minister, in these days, of fine language, and of polished rounded periods, resembles Nero, who when the city of Rome was starving, sent his galleys to Alexandria to bring back sand for the wrestlers, but not corn for hungry mouths. We have heard many a discourse that has been very fine indeed, as a moral essay, but it has had no food in it for the poor hungry mouths of God's people. One has but very little opinion of the present race of professing Christians when you see their frequent changes. I know men at this day who hear an Arminian with the greatest possible delight—"Such a dear, good, earnest man!" And if a Calvinist preaches the next Sunday, who contradicts every word the other man said—"Oh, he is such a precious creature!" because he happens to have a great flow of words. And then comes another who happens to be a hyper-Calvinist, and who says most extraordinary things—"He is a precious child of God, he preaches admirably!" And then there comes afterwards a Pelagian, or almost an Arian, and it is just the same—they take it all in, and delight in it. The reason is, because these people never taste the word of God at all. They look at it, but so long as they do not taste it and feed on it they know nothing of it. If they fed on the Word, they would have their senses exercised by reason of the use, and they would be able to discern between the good and the evil, the precious and the vile. Many of our Calvinistic preachers do not feed God's people. They believe in election, but they do not preach it. They think particular redemption true, but they lock it up in the chest of their creed, and never bring it out in their ministry. They hold final perseverance, but they persevere in keeping quiet about it. They think there is such a thing as effectual calling, but they do not think they are called effectually to preach it. The great fault we find with many is, that they do not speak right out what they do believe. You could not know if you heard them fifty times what were the doctrines of the gospel, or what was their system of salvation. And hence God's people get starved. And all the while the only remedy they have for the poor, weak, starving child of God, is a long whip. They are always cracking this whip with the loud sound of "do this! do that! and do the other!" If they would put the whip in the manger and feed God's people, then they would be able run the heavenly race. But now it is all whip and no corn, and no creature can subsist upon that. No child of God can ever grow strong in grace with mere exhortation, if it be not associated with good old-fashioned doctrine. I should like to hear all our pulpits sounding with the old-fashioned doctrine of John Owen, and of such men as Bunyan, and Charnock, and Goodwin, and those men of olden times who knew the truth and dared to preach it fully. There were giants in those days. In every parish church in the city of London, and in this borough, too, you might have found men who were no children in divinity, but masterly men, each of them able to declare the word of God with the authority of a master in Israel. Now where find we such? We labour and we strive, we dig, we toil, we seek to be something, and we end in being nothing. And so it must be as long as hands are weak and knees are feeble; and so also must this be as long as good doctrine is denied us, and truth is kept back in the ministry. Feed God's children well; give them comfort; give them much to feed upon of the sweet things of the kingdom of God; and then they will grow strong, then they will begin to work.
