“Is not the Lord your God with You?”-1 Chronicles 22:18

Here is David most anxious about the building of the temple at Jerusalem; he is not permitted to erect it himself, and therefore he sets to work with diligent care to gather together the gold and the silver, the brass and the iron, the timber and the stone, that would be required. He also instructed the workmen who would be needed, so that, when he was gone, and his son Solomon had ascended the throne, the temple might be built. Did David live in vain? Can it be truly said that he failed in the grandest project of his life? Assuredly not; he did all that he was permitted to do, and by making those elaborate preparations, he was really the means of the building of the temple.

Let every man and every woman among us judge of our life, not merely from that little narrow piece of it which we ourselves live, for that is but a span; but let us judge it by its connection with other lives that may come after our own. If we cannot do all we wish, let us do all we can, in the hope that someone who shall succeed us may complete the project that is so dear to our heart. That is a blessed prayer which Moses wrote in the 90th Psalm, “Let Thy work appear unto Thy servants, and Thy glory unto their children.” We shall be quite satisfied to do the work, and scarcely see the glory, if we may but know that, in another generation, the work that we shall have done shall produce glory to God which shall be seen among the sons of men. ~ C.H. Spurgeon
