Nation after nation rises, enters and occupies a place among the nations of the earth, falls, and is only known in the faithful records of history. Generation after generation comes forth, enters upon the great theatre of life, throngs the world for a little while, falls in death and passes into eternity. Upon an average, about once in thirty-three years, the whole of the inhabitants of the earth, or as many as are upon it at any one time, over one billion souls, are carried beyond the reach of all missionary effort—beyond the reach of all repentance—all gospel invitations, and so many as are not saved, beyond all possibility of salvation. During the same short period, the preachers, missionaries, writers and professors of religion of one generation are all born where no mistakes can be corrected, and no amendment for wrongs done, or time trifled away, can ever be made. Taking off from this time, eighteen years for childhood, only leaves about fifteen years for the vast work of personal preparation, for a state of boundless duration in the pure and holy society of just men made perfect, the angels of God, Jesus the mediator of the New Covenant, and God, the Judge of all. It also leaves about the same length of time for the good and virtuous, those with the love of God in their hearts, and lovers of mankind to make an effort to save our race. In this view of the subject—and no other can be justly taken—it will readily be perceived that what we do _must be done quickly_. Those who do anything for mankind, must engage in the work immediately and with energy. All who intend laying up a good foundation against the time to come—laying up treasure in heaven to which they can go, and upon which they can rely when their temporal supports shall all fail, must commence the work immediately, persevere in it, and abound during the short space afforded them. There must be no delay, for there is simply time enough to do what must be done immediately, if done at all. Those who have never prepared to meet God, have still greater reason to enter at once upon the examination of the subject. With them, everything to secure their eternal happiness, so far as their own action is concerned, is yet to be done. How short the time, in view of the amount to be done; and how carefully every moment should be employed by every person who has not been reconciled to God. What vast multitudes, throng our streets, lanes and highways, who have never seriously thought upon, much less taken the elementary steps, to come to God, and who will remain in their present condition, unless arrested in their thoughtless career, by those who have already tested the good word of God, and felt the power of the world to come. What an everlasting reason we find here for a most energetic, persevering, and godly effort to rescue them and bring them to God. THE GRAND WORK BEFORE US.
