We notice again--where the inheritance is situated--"in the light." There are several possible ways of connecting that clause with the preceding. But without discussing these, it may be enough to point out that the most satisfactory seems to be to regard it as specifying the region in which the inheritance lies. It lies in a realm where purity and knowledge and gladness dwell undimmed and unbounded by an envious ring of darkness. For these three are the triple rays into which, according to the Biblical use of the figure, that white beam may be resolved.
From this there follows that it is capable of being possessed only by _saints_. There is no merit or desert which makes men worthy of the inheritance, but there is a congruity, or correspondence between character and the inheritance. If we rightly understand what the essential elements of "heaven" are, we shall have no difficulty in seeing that the possession of it is utterly incompatible with anything but holiness. The vulgar ideas of what heaven is, hinder people from seeing how to get there. They dwell upon the mere outside of the thing, they take symbols for realities and accidents for essentials, and so it appears an arbitrary arrangement that a man must have faith in Christ to enter heaven. If it be a kingdom of light, then only souls that love the light can go thither, and until owls and bats rejoice in the sunshine, there will be no way of being fit for the inheritance which is light, but by ourselves being "light in the Lord." Light itself is a torture to diseased eyes. Turn up any stone by the roadside and we see how unwelcome light is to crawling creatures that have lived in the darkness till they have come to love it.
Heaven is God and God is heaven. How can a soul possess God, and find its heaven in possessing Him? Certainly only by likeness to Him, and loving Him. The old question, "Who shall stand in the Holy Place?" is not answered in the gospel by reducing the conditions, or negativing the old reply. The common sense of every conscience answers, and Christianity answers, as the Psalmist does, "He that hath clean hands and a pure heart."
One more step has to be taken to reach the full meaning of these words, namely, the assertion that men who are not yet perfectly pure are already fit to be partakers of the inheritance. The tense of the verb in the original points back to a definite act by which the Colossians were made meet, namely, their conversion; and the plain emphatic teaching of the New Testament is that incipient and feeble faith in Christ works a change so great, that through it we are fitted for the inheritance by the impartation of a new nature, which, though it be but as a grain of mustard seed, shapes from henceforth the very inmost centre of our personal being. In due time that spark will convert into its own fiery brightness the whole mass, however green and smokily it begins to burn. Not the absence of sin, but the presence of faith working by love, and longing for the light, makes fitness. No doubt flesh and blood cannot inherit the Kingdom of God, and we must put off the vesture of the body which has wrapped us during the wild weather here, before we can be fully fit to enter the banqueting hall; nor do we know how much evil which has not its seat in the soul may drop away therewith--but the spirit is fit for heaven as soon as a man turns to God in Christ. Suppose a company of rebels, and one of them, melted by some reason or other, is brought back to loyalty. He is fit by that inward change, although he has not done a single act of loyalty, for the society of loyal subjects, and unfit for that of traitors. Suppose a prodigal son away in the far off land. Some remembrance comes over him of what home used to be like, and of the bountiful house-keeping that is still there; and though it may begin with nothing more exalted than an empty stomach, if it ends in "I will arise and go to my Father," at that instant a gulf opens between him and the riotous living of "the citizens of that country," and he is no longer fitted for their company. He is meet for the fellowship of his father's house, though he has a weary journey before he gets there, and needs to have his rags changed, and his filth washed off him, ere he can sit down at the feast.
