'The remnant of Jacob shall be in the midst of many people as a dew from the Lord, that tarrieth not for man, nor waiteth for the sons of men.'--MICAH v. 7. The simple natural science of the Hebrews saw a mystery in the production of the dew on a clear night, and their poetic imagination found in it a fit symbol for all silent and gentle influences from heaven that refreshed and quickened parched and dusty souls. Created by an inscrutable process in silence and darkness, the dewdrops lay innumerable on the dry plains and hung from every leaf and thorn, each little globule a perfect sphere that reflected the sun, and twinkled back the beams in its own little rainbow. Where they fell the scorched vegetation lifted its drooping head. That is what Israel is to be in the world, says Micah. He saw very deep into God's mind and into the function of the nation. It may be a question as to whether the text refers more especially to the place and office of Israel when planted in its own land, or when dispersed among the nations. For, as you see, he speaks of 'the remnant of Jacob' as if he was thinking of the survivors of some great calamity which had swept away the greater portion of the nation. Both things are true. When settled in its own land, Israel's office was to teach the nations God; when dispersed among the Gentiles, its office ought to have been the same. But be that as it may, the conception here set forth is as true to-day as ever it was. For the prophetic teachings, rooted though they may be in the transitory circumstances of a tiny nation, are 'not for an age, but for all time,' and we get a great deal nearer the heart of them when we grasp the permanent truths that underlie them, than when we learnedly exhume the dead history which was their occasion. Micah's message comes to all Christians, and very eminently to English Christians. The subject of Christian missions is before us to-day, and some thoughts in the line of this great text may not be inappropriate. We have here, then, I. The function of each Christian in his place.
