We want two things to take us to heaven; a title to it, and a meetness for it. Our only title to heaven is the blood and righteousness of the Son of God—that blood which "cleanseth from all sin," and that righteousness which "justifies us from all things from which we could not be justified by the law of Moses." Nothing unclean or defiled can enter heaven. This is God's own testimony: "There shall in no wise enter into it anything that defileth, neither whatsoever worketh abomination, or maketh a lie, but they which are written in the Lamb's book of life" (Rev. 21:27).
But besides the title, there must be also a meetness for this heavenly city, according to the words of the apostle: "Giving thanks unto the Father, which hath made us meet to be partakers of the inheritance of the saints in light" (Col. 1:12).
Whilst here below, then, we must learn to sing some notes of that joyous anthem which will issue in full, uninterrupted harmony from the hearts and lips of the redeemed in the realms above, when that glorious company will ever cry, "Alleluia! Salvation, and glory, and honour, and power unto the Lord our God." If we are to sit down among those blessed ones who are called unto the marriage supper of the Lamb, not only must we be "arrayed in fine linen, clean and white, for the fine linen is the righteousness of saints," but we must have had "the kingdom of God, which is righteousness and peace and joy in the Holy Ghost" (Rom. 14:17), set up in our hearts.
