8. The religion of heaven consists very much in affection.
There is doubtless true religion in heaven, and true religion in its utmost purity and perfection. But according to the Scripture representation of the heavenly state, the religion of heaven consists chiefly in holy and mighty love and joy, and the expression of these in most fervent and exalted praises. So that the religion of the saints in heaven, consists in the same things with that religion of the saints on earth, which is spoken of in our text, viz., love, and "joy unspeakable and full of glory." Now it would be very foolish to pretend, that because the saints in heaven be not united to flesh and blood, and have no animal fluids to be moved (through the laws of union of soul and body) with those great emotions of their souls, that therefore their exceeding love and joy are no affections. We are not speaking of the affections of the body, but of the affections of the soul, the chief of which are love and joy. When these are in the soul, whether that be in the body or out of it, the soul is affected and moved. And when they are in the soul, in that strength in which they are in the saints in heaven, the soul is mightily affected and moved, or, which is the same thing, has great affections. It is true, we do not experimentally know what love and joy are in a soul out of a body, or in a glorified body; i.e., we have not had experience of love and joy in a soul in these circumstances; but the saints on earth do know what divine love and joy in the soul are, and they know that love and joy are of the same kind with the love and joy which are in heaven, in separate souls there. The love and joy of the saints on earth, is the beginning and dawning of the light, life, and blessedness of heaven, and is like their love and joy there; or rather, the same in nature, though not the same with it, or like to it, in degree and circumstances. This is evident by many Scriptures, as Prov. 4:18; John 4:14, and chap. 6:40, 47, 50, 51, 54, 58; 1 John 3:16; 1 Cor. 13:8-12. It is unreasonable therefore to suppose, that the love and joy of the saints in heaven, not only differ in degree and circumstances, from the holy love and joy of the saints on earth, but is so entirely different in nature, that they are no affections; and merely because they have no blood and animal spirits to be set in motion by them, which motion of the blood and animal spirits is not of the essence of these affections, in men on the earth, but the effect of them; although by their reaction they may make some circumstantial difference in the sensation of the mind. There is a sensation of the mind which loves and rejoices, that is antecedent to any effects on the fluids of the body; and this sensation of the mind, therefore, does not depend on these motions in the body, and so may be in the soul without the body. And wherever there are the exercises of love and joy, there is that sensation of the mind, whether it be in the body or out; and that inward sensation, or kind of spiritual sense, or feeling, and motion of the soul, is what is called affection: the soul when it thus feels (if I may say so), and is thus moved, is said to be affected, and especially when this inward sensation and motion are to a very high degree, as they are in the saints in heaven. If we can learn anything of the state of heaven from the Scripture, the love and joy that the saints have there, is exceeding great and vigorous; impressing the heart with the strongest and most lively sensation of inexpressible sweetness, mightily moving, animating and engaging them, making them like a flame of fire. And if such love and joy be not affections, then the word affection is of no use in language. Will any say, that the saints in heaven, in beholding the face of their Father, and the glory of their Redeemer, and contemplating his wonderful works, and particularly his laying down his life for them, have their hearts nothing moved and affected by all which they behold or consider?
Hence, therefore, the religion of heaven, consisting chiefly in holy love and joy, consists very much in affection; and therefore, undoubtedly, true religion consists very much in affection. The way to learn the true nature of anything, is to go where that thing is to be found in its purity and perfection. If we would know the nature of true gold we must view it, not in the ore, but when it is refined. If we would learn what true religion is, we must go where there is true religion, and nothing but true religion, and in its highest perfection, without any defect or mixture. All who are truly religious are not of this world, they are strangers here, and belong to heaven; they are born from above, heaven is their native country, and the nature which they receive by this heavenly birth, is a heavenly nature, they receive an anointing from above; that principle of true religion which is in them, is a communication of the religion of heaven; their grace is the dawn of glory; and God fits them for that world by conforming them to it.
9. This appears from the nature and design of the ordinances and duties, which God hath appointed, as means and expressions of true religion.
To instance in the duty of prayer: it is manifest, we are not appointed in this duty, to declare God's perfections, his majesty, holiness, goodness, and all-sufficiency, and our own meanness, emptiness, dependence, and unworthiness, and our wants and desires, to inform God of these things, or to incline his heart, and prevail with him to be willing to show us mercy; but suitably to affect our own hearts with the things we express, and so to prepare us to receive the blessings we ask. And such gestures and manner of external behavior in the worship of God, which custom has made to be significations of humility and reverence, can be of no further use than as they have some tendency to affect our own hearts, or the hearts of others.
And the duty of singing praises to God seems to be appointed wholly to excite and express religious affections. No other reason can be assigned why we should express ourselves to God in verse, rather than in prose, and do it with music but only, that such is our nature and frame, that these things have a tendency to move our affections.
The same thing appears in the nature and design of the sacraments, which God hath appointed. God, considering our frame, hath not only appointed that we should be told of the great things of the gospel, and of the redemption of Christ, and instructed in them by his word; but also that they should be, as it were, exhibited to our view, in sensible representations, in the sacraments, the more to affect us with them.
And the impressing divine things on the hearts and affections of men, is evidently one great and main end for which God has ordained that his word delivered in the holy Scriptures, should be opened, applied, and set home upon men, in preaching. And therefore it does not answer the aim which God had in this institution, merely for men to have good commentaries and expositions on the Scripture, and other good books of divinity; because, although these may tend as well as preaching to give men a good doctrinal or speculative understanding of the things of the word of God, yet they have not an equal tendency to impress them on men's hearts and affections. God hath appointed a particular and lively application of his word to men in the preaching of it, as a fit means to affect sinners with the importance of the things of religion, and their own misery, and necessity of a remedy, and the glory and sufficiency of a remedy provided; and to stir up the pure minds of the saints, and quicken their affections, by often bringing the great things of religion to their remembrance, and setting them before them in their proper
