My text is very significantly followed by a for,' which gives the reason of the knowledge in a very remarkable manner. We know for in this we groan, earnestly desiring to be clothed upon with our house, which is from heaven.' Now that singular collocation of ideas may be set forth thus--whatever longing there is in a Christian, God-inspired soul, that longing is a prophecy of its own fulfilment. We know that there is a house, because of the yearning, which is deepest and strongest when we are nearest God, and likest what He would have us to be--the yearning to be clothed upon with our house which is fromheaven.' That is a truth that goes a long way ,though to enlarge on it is irrelevant to our present purpose. It has its limitations, as is obvious from the context, in which are human elements which are not destined to be gratified, mingled with the yearning, which is of God, and which is destined to be satisfied. But this at least we may firmly hold by, that just because God will not put men to confusion intellectually, and does not let them entertain uncherished, still less Himself foster and excite--longings which He does not mean to gratify, a Christian yearning for immortality is, to the man who feels it, a declaration that immortality is sure for him. Delight thyself in the Lord, and He shall give thee the desires of thine heart.' Whatsoever, in touching Him, we do deeply long for may have blended with it human elements, which will be dispersed unsatisfied, but the substance of it is a prophecy of its own fulfilment. And as surely as the stork in the heavens, flying southward, will reach the sunny lands which draw it from the grim northern winter, so surely may a man say, I know that I have a house in heaven, because I long for it, and shrink from being found naked.'
Of course such longing, such aspiration and revulsion are no proofs of a fact except there be some fact which changes them from mere vague desires, and makes these solid certainties. And such a fact we have in that which is the only proof that the world has received, of the persistence of life through death and the continuance of personal identity unchanged by the grave, and that is the Resurrection of Jesus Christ from the dead. Our faith in immortality does not depend merely on our own subjective desires and longings, but these desires and longings are quickened, confirmed, and certified by this great fact that Jesus Christ has risen from the dead; and therefore we know that the yearnings in us are not in vain. So we come to this certitude, first, by reason of his experience; and, second, by reason of the longings which that experience fosters, if it does not kindle, within our hearts.
And let no man take exception to the Apostle's word here, we know,' or tell us that Knowledge is of the things we see.' That is true, and not true. It is true in regard to what arrogates to itself the name of science. And we are willing to admit the limitation if the men who insist upon it will, on their sides, admit that there are other sources of certitude than so-called facts,' by which they mean merely material facts. If it is meant to assert that we are less sure of the love of God, of immortality, than we are of the existence of this piece of wood, or that flame of gas; then I humbly venture to say that there is another region of facts than those which are appreciable by sense; that the evidence upon which we rest our certitude of immortal blessedness is quite as valid, quite as true, quite as able to bear the weight of a leaning heart as anything that can be produced, in the nature of evidence, for the things round us. It is not, We fancy, we believe, we hope, we are pretty nearly sure,' but it is We know that we have a building of God.'
