While his most well-known sermon is about hell, Jonathan Edwards seems to me to be most eloquent, passionate, and happy when writing about heaven. Three examples:
This, therefore, may be your consolation, that in heaven your heart shall be enlarged, you shall be enabled to praise him in an immensely more perfect and exalted manner than you can do in this world. You shall not be troubled with such a dead, dull heart, with so much coldness, so many clogs and burdens from corruption, and from a earthly mind; with a wandering, unsteady heart; with so much darkness and so much hypocrisy. You shall be one of that vast assembly that praise God so fervently, that their voice is “as the voice of many waters, and as the voice of mighty thunderings.” [“Praise, One of the Chief Employments of Heaven”]
…a godly man prefers God before anything else that might be in heaven. Not only is there nothing actually in heaven, which is in his esteem equal with God; but neither is there any of which he can conceive as possible to be there, which by him is esteemed and desired equally with God.…If it were empty of God, it would indeed be an empty melancholy place. — The godly have been made sensible, as to all creature-enjoyments, that they cannot satisfy the soul; and therefore nothing will content them but God. Offer a saint what you will, [but] if you deny him God, he will esteem himself miserable. God is the center of his desires; and as long as you keep his soul from its proper center, it will not be at rest. [“God the Best Portion of the Christian”]
The heaven I desired was a heaven of holiness; to be with God, and to spend my eternity in divine love, and holy communion with Christ. My mind was very much taken up with contemplations on heaven, and the enjoyments there; and living there in perfect holiness, humility, and love; and it used at that time to appear a great part of the happiness of heaven, that there the saints could express their love to Christ.
