The other preliminary and condition is 'being sober,' which of course you have to extend to its widest possible signification, implying not merely abstinence from, or moderate use of, intoxicants, or material good for the appetites, but also the withdrawing of one's self sometimes wholly from, and always restraining one's self in the use of, the present and the material. A man has only a given definite quantity of emotion and interest to expend, and if he flings it all away on the world he has none left for Heaven. He will be like the miller that spoils some fair river, by diverting its waters into his own sluice, in order that he may grind some corn. If you have the faintest film of dust on the glass of the telescope, or on its mirror, if it is a reflecting one, you will not see the constellations in the heavens; and if we have drawn over our spirits the film of earthly absorption, all these bright glories above will, so far as we are concerned, cease to be.
So, brethren, there is a solemn responsibility laid upon us by the gift of that great faculty of looking before and after. What did God make you and me capable of anticipating the future for? That we might let our hopes run along the low levels, or that we might elevate them and twine them round the very pillars of God's Throne; which? I do not find fault with you because you hope, but because you hope so meanly, and about such trivial and transitory things. I remember I once saw a sea-bird kept in a garden, confined within high walls, and with clipped wings, set to pick up grubs and insects. It ought to have been away out, hovering over the free ocean, or soaring with sunlit wing to a height where earth became a speck, and all its noises were hushed. That is what some of you are doing with your hope, degrading it to earth instead of letting it rise to God; enter within the veil, and gaze upon the glory of the 'inheritance incorruptible and undefiled.'
