Here, from the pen of Jonathan Edwards, are several ways for the Christian to cultivate a love for heaven and a holy piety that fits us for that realm. These are manifestly helpful to the Christian seeking to learn how to become more heavenly-minded, in the best sense of the term.
“First, let not your heart go after the things of this world, as your chief good. Indulge not yourself in the possession of earthly things as though they were to satisfy your soul. This is the reverse of seeking heaven; it is to go in a way contrary to that which leads to the world of love. If you would seek heaven, your affections must be taken off from the pleasures of the world. You must not allow yourself in sensuality, or worldliness, or the pursuit of the enjoyments or honors of the world, or occupy your thoughts or time in heaping up the dust of the earth. You must mortify the desires of vain-glory, and become poor in spirit and lowly in heart.
Second, you must, in your meditations and holy exercises, be much engaged in conversing with heavenly persons, and objects, and enjoyments.
Third, be content to pass through all difficulties in the way to heaven.
Fourth, In all your way let your eye be fixed on Jesus, who has gone to heaven as your forerunner. Look to him. Behold his glory in heaven, that a sight of it may stir you up the more earnestly to desire to be there.
Fifth, If you would be in the way to the world of love, see that you live a life of love-of love to God, and love to men. All of us hope to have part in the world of love hereafter, and therefore we should cherish the spirit of love, and live a life of holy love here on earth. This is the way to be like the inhabitants of heaven, who are now confirmed in love forever. Only in this way can you be like them in excellence and loveliness, and like them, too, in happiness, and rest, and joy. By living in love in this world you may be like them, too, in sweet and holy peace, and thus have, on earth, the foretastes of heavenly pleasures and delights. Thus, also, you may have a sense of the glory of heavenly things, as of God, and Christ, and holiness; and your heart be disposed and opened by holy love to God, and by the spirit of peace and love to men, to a sense of the excellence and sweetness of all that is to be found in heaven. Thus shall the windows of heaven be as it weere opened, so that its glorious light shall shine in upon your soul. Thus you may have the evidence of your fitness for that blessed world, and that you are actually on the way to its possession. And being this made meet, through grace, for the inheritance of the saints in light, when a few more days shall have passed away, you shall be with them in their blessedness forever. Happy, thrice happy those, who shall thus be found faithful to the end, and then shall be welcomed to the joy of their Lord! There “they shall hunger no more, neither thrist anymore; neither shall the sun light on them, nor any heat. For the lamb which is in the midst of the throne shall feed them, and lead them to living fountains of waters, and God shall wipe away all tears from their eyes.”
