"And an highway shall be there, and a way, and it shall be called The way of holiness: the unclean shall not pass over it; .... but the redeemed shall walk there." Isaiah 35:8, 9.
HEAVEN is the abode of a renewed people; it is a holy place, and the home of the holy; and before the sinner can have any real fitness for heaven, any well-grounded hope of glory, he must be a partaker of a nature harmonizing with the purity, and corresponding with the enjoyments, of heaven. Heaven would be no heaven to a carnal mind, to an unsanctified heart. Were it possible to translate an unconverted individual from this world to the abodes of eternal glory, overwhelmed with the effulgence of the place, and having no fellowship of feeling with the purity of its enjoyments, and the blessedness of its society, he would exclaim—"Take me hence—it is not the place for me—I have no sympathy with it—I have no fitness for it—I have no pleasure in it." Solemn thought! But the Christian is a renewed creature—he is a partaker of the Divine nature; he has sympathies, affections, and desires, imparted to him by the Spirit, which assimilate him to the happiness and purity of heaven. It is impossible but that he must be there. He possesses a nature unfit for earth, and congenial only with heaven. He is the subject of a spiritual life that came from, and now ascends to, heaven.
All its aspirations are heavenly—all its breathings are heavenly—all its longings are heavenly; and thus it is perpetually soaring towards that world of glory from where it came, and for which God is preparing it. So that it would seem utterly impossible but that a renewed man must be in heaven, since he is the partaker of a nature fitted only for the regions of eternal purity and bliss. But what is it that gives the Christian a valid deed, a right of possession, to eternal glory? It is his justification by faith through the imputed righteousness of Christ. This is the only valid title to eternal glory which God will admit—the righteousness of His dear Son imputed to him that believes. Here is the grand fitness of a poor, lost, polluted, undone sinner; the fitness that springs from the spotless righteousness of the Lord Jesus, "who of God is made unto us wisdom, and righteousness, and sanctification, and redemption." "He has made Him to be sin for us, who knew no sin, that we might be made the righteousness of God in Him." Behold, then, beloved, the high vantage-ground on which a saint of God stands, with regard to his hope of heaven. He stands out of his own righteousness in the righteousness of another. He stands accepted in the Accepted One, he stands justified in the Justified One, and justified, too, by God, the great Justifier.
The spiritual life which God has breathed into our souls will never rest until it reaches its full and perfect development. Deep as are its pulsations, holy as are its breathings, it is yet but in its infancy, compared with that state of perfection to which it is destined. The highest state of sanctification to which the believer can arrive here is but the first dawn of day, contrasted with the "far more exceeding and eternal weight of glory," which will burst upon him in a world of perfect holiness. Heaven will complete the work which sovereign grace has begun upon earth. Heaven is the consummation of the spiritual life of the believer.
