That strikes one as somewhat strange. I very much doubt whether the ordinary run of good people do recognise it as being as imperative a duty for them to cultivate hope as to cultivate any other Christian excellence or virtue. For one man that sets himself deliberately and consciously to brighten up, and to make more operative in his daily life, the hope of future blessedness, you will find a hundred that set themselves to other kinds of perfecting of their Christian character. And yet, surely, there do not need any words to enforce the fact that this hope full of immortality is no mere luxury which a Christian man may add to the plain fare of daily duty or leave untasted according as he likes, but that it is an indispensable element in all vigorous and life-dominating Christian experience.
I do not need to dwell upon that, except just to suggest that such a vividness and continuity of calm anticipation of a certain good beyond the grave is one of the strongest of all motives to the general robustness and efficacy of a Christian life. People used to say a few years ago, a great deal more than they do now, that the Christian expectation of Heaven was apt to weaken energy upon earth, and they used to sneer at us, and talk about our other worldliness' as if it were a kind of weakness and defect attached to the Christian experience. They have pretty well given that up now. Anti-Christian sarcasm, like everything else, has its fashions, and other words of reproach and contumely have now taken the place of that. The plain fact is that no man sees the greatness of the present, unless he regards it as being the vestibule of the future, and that this present life is unintelligible and insignificant unless beyond it, and led up to by it, and shaped through it, there lies the eternal life beyond. The low fiat plain is dreary and desolate, featureless and melancholy, when the sky above it is filled with clouds. But sweep away the cloud-rack, and let the blue arch itself above the brown moorland, and all glows into lustre, and every undulation is brought out, and tiny shy forms of beauty are found in every corner. And so, if you drape Heaven with the clouds and mists bern of indifference and worldliness, the world becomes mean, but if you dissipate the cloud and unveil heaven, earth is greatened. If the hope of the grave that is to be brought unto you at the revelation of Jesus Christ shines out above all the flatness of earth, then life becomes solemn, noble, worthy of, demanding and rewarding, our most strenuous efforts. No man can, and no man will, strike such effectual blows on things present as the man, the strength of whose arm is derived from the conviction that every stroke of the hammer on things present is shaping that which will abide with him for ever.
My text not only enjoins this hope as a duty, but also enjoins the perfection of it as being a thing to be aimed at by all Christian people. What is the perfection of hope? Two qualities, certainty and continuity. Certainty; the definition of earthly hope is an anticipation of good less than certain, and so, in all the operations of this great faculty, which are limited within the range of earth, you get blended as an indistinguishable throng, hopes and fears that kindle hope,' and that too often kill it. But the Christian has a certain anticipation of certain good, and to him memory may be no more fixed than hope, and the past no more unalterable and uncertain than the future. The motto of our hope is not the perhaps,' which is the most that it can say when it speaks the tongue of earth, but the verily! verily!' which comes to its enfranchised lips when it speaks the tongue of Heaven. Your hope, Christian man, should not be the tremulous thing that it often is, which expresses itself in phrases like Well I do not know, but I tremblingly hope,' but it should say, I know and am sure of the rest that remaineth, not because of what I am, but because of what He is.'
Another element in the perfection of hope is its continuity. That hits home to us all, does it not? Sometimes in calm weather we catch a sight of the gleaming battlements of the City which hath foundations,' away across the sea, and then mists and driving storms come up and hide it. There is a great mountain in Central Africa which if a man wishes to see he must seize a fortunate hour in the early morning, and for all the rest of the day it is swathed in clouds, invisible. Is that like your hope, Christian man and woman, gleaming out now and then, and then again swallowed up in the darkness? Brethren! these two things, certainty and continuity, are possible for us. Alas! that they are so seldom enjoyed by us.
