III. Lastly, we have here the heirs' present knowledge of their future blessedness. The Apostle asks that these men may know a thing that clearly seems unknowable. It is an impossible petition, we might be ready to say, because it is clear enough that there can be no true knowledge of the conditions and details of that future life. The dark mountains that lie between us and it hide their secret well, and few or no stray beams have reached us. An unborn babe, or a chrysalis in a hole in the ground or in a chink of a tree, might think as wisely about its future condition as we can do about that life beyond. There can be no knowledge until there is experience. What, then, does Paul mean by framing such a petition as this? The answer is found in noticing that the knowledge which he is imploring here is a consequence of a previous knowledge. For, in a former verse, he prays that these men may have 'the spirit of wisdom in the knowledge of God'; and when they have got the knowledge of God he thinks that they will have got the knowledge of 'the riches of the glory of His inheritance in the saints.' Now, turn that into other words, and it is just this, that the knowledge of God, which comes by faith and love here, is in kind so identical with the fullest and loftiest riches of the knowledge of Him hereafter, that, if we have the one, we are not without the other. The one is in germ, the other, no doubt, full blown; the one is the twinkling of the rushlight, as it were, the other is the blaze of the sunshine. The two states of being are so correspondent that from the one we draw our clearest knowledge of the other. There are telescopes, in using which you do not look up when you want to see the stars, but down on to a reflecting mirror, and there you see them. Such a reflecting mirror, though it be sometimes muddied and dimmed and always very small, are the experiences of the Christian soul here. So, dear friends, if we want to know as much as may be known of the blessedness of heaven, let us seek to possess as much as may be possessed of the knowledge and love of God on earth. Then we shall know the centre, at any rate; and that is light, though the circumference may be very dark. Much will remain obscure. That is of very small consequence to Hope, which does not need information half so much as it needs assurance. Like some flower in the cranny of the rock, it can spread a broad bright blossom on little soil, if only it be firmly rooted.
