Preaching on Ezekiel 34:26, “And I will make them and the places round about my hill a blessing; and I will cause the shower to come down in his season; there shall be showers of blessing”, Spurgeon offers this:

The object of God, in choosing a people before all worlds, was not only to save that people, but through them to confer essential benefits upon the whole human race. When he chose Abraham, he did not elect him simply to be God’s friend, and the recipient of peculiar privileges; but he chose him to make him, as it were, the conservator of the truth. He was to be the ark in which the truth should be hidden. He was to be the keeper of the covenant on behalf of the whole world; and when God chooses any men by his sovereign, electing grace, and makes them Christ’s, he does it not only for their own sake, that they may be saved, but for the world’s sake. For, know ye not that “ye are the light of the world;”–“A city set upon a hill, which cannot be hid?” “Ye are the salt of the earth;” and when God makes you salt, it is not only that ye may have salt in yourselves, but that like salt ye may preserve the whole mass. If he makes you leaven, it is that, like the little leaven, you may leaven the whole lump. Salvation is not a selfish thing; God does not give it for us to keep to ourselves, but that we may thereby be made the means of blessing to others; and the great day shall declare that there is not a man living on the surface of the earth but has received a blessing in some way or other through God’s gift of the gospel.

Eschatology should be determined less in the light of difficult millennial passages and more in the light of God’s promises and the efficacy of the atonement. Spurgeon was no postmillenialist by name, but he expected the Gospel to do the work of blessing every family on the earth, a consequence required by no other eschatalogical doctrine. I should be quick to add that all evangelistic progress is made by sacrificial preaching and living, that no crop comes unless a seed goes into the ground and “dies.” Jesus went into the ground and died, and biblical hope is nothing other than a bumper crop.
