Charles H. Spurgeon on Psalms 119:111

As an heritage. Why the divine testimonies should be called by the Psalmist an inheritance; why he brings them within the compass of this notion, may not So easily be understood; for the word of God points out the inheritance, but it is not the inheritance itself. Yes, there is good reason to be given for the expression, were there no more than this, that we consider the inestimable comfort, and heavenly treasure that is to be found in the word of God; it is a rich mine of all celestial treasure, it is a storehouse of all good things, of all saving knowledge. All privileges whatsoever they are that we can expect on earth or heaven, they are all contained in the word of God: here is ground enough why it is called an inheritance; he hath a good heritage that hath all these.

Yet there is a better reason than this; for if it be so that heaven is our inheritance, then the word of God is; because it is the word that points out heaven, that gives the assurance of heaven: we have in the word of God all the evidences of heaven. Whatsoever title any saint hath to heaven, he hath it in and out of the word of God. There are the evidences in the word of God; both the evidence of discovery, it is the holy terrier of the celestial Canaan, and the evidence of assurance, it is as a sacred bond or indenture between God and his creature. St. Gregory said wittily, when he called it God's epistle that he sent to man for the declaration of his will and pleasure, he might as well have called it God's deed of gift, whereby he makes over and conveys to us all those hopes that we look for in heaven. Whatsoever interest we have in God, in Christ, whatsoever hope of bliss and glory, whatsoever comfort of the Spirit, whatsoever proportion of grace, all are made over to us in the promises of the gospel, in the word of God.

Now put this together, look as in human affairs, evidences, though they be not properly the inheritance itself, yet they are called the inheritance, and are the inheritance, though not actually, yet virtually so; because all the title we have to an inheritance is in the deeds and evidences; therefore evidences are precious things. Though it be but a piece of paper, or parchment full of dust and worm eaten, yet it is as much worth sometimes as a county, as much worth as all a man's possessions besides. So likewise it is with the Scriptures; they are not actually and properly the inheritance itself, but they are via, the way to the kingdom. It is called the gospel of the kingdom, nay more, the kingdom itself: "The kingdom of God is come among you, "or "to you". Why the kingdom? Why the inheritance? By the same reason, both, because here we have the conveyance, here we have the deed, here we have the assurance of whatsoever title or claim we make to heaven. Richard Holdsworth.
