“God has given to mankind affections, for the same purpose which he has given all the faculties and principles of the human soul for, that they might be subservient to man’s chief end, and the great business for which God has created him, that is the business of religion.
And yet how common is it among mankind, that their affections are much more exercised and engaged in other matters, than in religion! In things which concern men’s worldly interest, their outward delights, their honor and reputation, and their natural relations, they have their desires eager, their appetites vehement, their love warm and affectionate, their zeal ardent.
In these things their hearts are tender and sensible, easily moved, deeply impressed, much concerned, very sensibly affected, and greatly engaged; much depressed with grief at worldly losses, and highly raised with joy at worldly successes and prosperity.
But how insensible and unmoved are most men, about the great things of another world! How dull are their affections! How heavy and hard their hearts in these matters! Here their love is cold, their desires languid, their zeal low, and their gratitude small.
How they can sit and hear of the infinite height and depth and length and breadth of the love of God in Christ Jesus, of His giving His infinitely dear Son, to be offered up a sacrifice for the sins of men, and of the unparalleled love of the innocent, holy and tender Lamb of God, manifested in His dying agonies, His bloody sweat, His loud and bitter cries, and bleeding heart, and all this for enemies, to redeem them from deserved, eternal burnings, and to bring to unspeakable and everlasting joy and glory… and yet be cold, and heavy, insensible, and regardless!
Where are the exercises of our affections proper, if not here? What is it that does more require them? And what can be a fit occasion of their lively and vigorous exercise, if not such a one as this? Can anything be set in our view, greater and more important? Anything more wonderful and surprising? Or more nearly concerning our interest?
Is there anything, which Christians can find in heaven or earth, so worthy to be the objects of their admiration and love, their earnest and longing desires, their hope, and their rejoicing, and their fervent zeal, as those things that are held forth to us in the gospel of Jesus Christ?
The glory and beauty of the blessed Jehovah, which is most worthy in itself, to be the object of our admiration and love, is there exhibited in the most affecting manner that can be conceived of, as it appears shining in all its luster, in the face of an incarnate, infinitely loving, meek, compassionate, dying Redeemer.
All the virtues of the Lamb of God, His humility, patience, meekness, submission, obedience, love and compassion, are exhibited to our view.”
