Evangelism
Barnes on Isaiah 55:11
That whatever is his design in giving the gospel, it shall be accomplished. It is never spoken in vain, and never fails to produce the effect which he intends. The gospel is no more preached in vain than the rain falls in vain. And though that often falls on barren rocks, or on arid sands; on extended plains where no vegetation is produced, or in the wilderness ‘where no man is,’ and seems to our eyes in vain, yet it is not so. God has a design in each drop that falls on sands or rocks, as really as in the copious shower that falls on fertile fields. And so the gospel often falls on the hard and barren hearts of men. It is addressed to the proud, the sensual, the avaricious, and the unbelieving, and seems to be spoken in vain, and to return void unto God. But it is not so. He has some design in it, and that will be accomplished. It is proof of the fullness of his mercy. It leaves people without excuse, and justifies himself. Or when long presented - apparently long in vain - it ultimately becomes successful, and sinners are at last brought to abandon their sins, and to turn unto God. It is indeed often rejected and despised. It falls on the ears of people apparently as the rain falls on the hard rock, and there are, so to speak, large fields where the gospel is preached as barren and unfruitful of any spiritual good as the extended desert is of vegetation, and the gospel seems to be preached to almost entire communities with as little effect as is produced when the rains fall on the deserts of Arabia, or of Africa. But there will be better and happier times. Though the gospel may not now produce all the good effects which we may desire, yet it will be ultimately successful to the full wish of the widest benevolence, and the whole world shall be filled with the knowledge and the love of God.
Barnes on Amos 9:13
And they shall not follow only on one another, but shall all go on together in one perpetual round of toil and fruitfulness. There shall be one unceasing inpouring of riches; no break in the heavenly husbandry; labor shall at once yield fruit; the harvest shall but encourage fresh labor. The end shall come swiftly on the beginning; the end shall not close the past only, but issue forth anew. Such is the character of the toils of the Gospel. All the works of grace go on in harmony together; each helps on the other; in one, the fallow-ground of the heart is broken up; in another, seed is sown, the beginning of a holy conversation; in another, is the full richness of the ripened fruit, in advanced holiness or the blood of martyrs. And so, also, of the ministers of Christ, some are adapted especially to one office, some to another; yet all together carry on His one work. All, too, patriarchs, prophets, Apostles, shall meet together in one; they who, before Christ’s coming , “sowed the seed, the promises of the Blessed Seed to come,” and they who “entered into their labors,” not to displace, but to complete them; all shall rejoice together in that Seed which is Christ.
Torrey in Why God Used D.L. Moody
Oh, men and women! especially young men and young women, perhaps God is beginning to use you; very likely people are saying: “What a wonderful gift he has as a Bible teacher, what power he has as a preacher, for such a young man!” Listen: get down upon your face before God. I believe here lies one of the most dangerous snares of the Devil. When the Devil cannot discourage a man, he approaches him on another tack, which he knows is far worse in its results; he puffs him up by whispering in his ear: “You are the leading evangelist of the day. You are the man who will sweep everything before you. You are the coming man. You are the D. L. Moody of the day”; and if you listen to him, he will ruin you. The entire shore of the history of Christian workers is strewn with the wrecks of gallant vessels that were full of promise a few years ago, but these men became puffed up and were driven on the rocks by the wild winds of their own raging self-esteem.
