I came across this in Matthew Henry’s commentary on the Bible, in reference to 1 John 4:14-16. I’m going to quote the whole section because it’s well worth pondering on.
The history of the Lord Christ is the history of God’s love to us; all his transactions in and with his Son were but testifications of his love to us, and means to advance us to the love of God: God was in Christ reconciling the world unto himself, 2 Cor. 5:19. Hence we may learn,
1. That God is love (1 John 4:16); he is essential boundless love; he has incomparable incomprehensible love for us of this world, which he has demonstrated in the mission and mediation of his beloved Son. It is the great objection and prejudice against the Christian revelation that the love of God should be so strange and unaccountable as to give his own eternal Son for us; it is the prejudice of many against the eternity and the deity of the Son that so great a person should be given for us. It is, I confess, mysterious and unsearchable; but there are unsearchable riches in Christ. It is a pity that the vastness of the divine love should be made a prejudice against the revelation and the belief of it. But what will not God do when he designs to demonstrate the height of any perfection of his? When he would show somewhat of his power and wisdom, he makes such a world as this; when he would show more of his grandeur and glory, he makes heaven for the ministering spirits that are before the throne. What will he not do then when he designs to demonstrate his love, and to demonstrate his highest love, or that he himself is love, or that love is one of the most bright, dear, transcendent, operative excellencies of his unbounded nature; and to demonstrate this not only to us, but to the angelic world, and to the principalities and powers above, and this not for our surprise for a while, but for the admiration, and praise, and adoration, and felicity, of our most exalted powers to all eternity? What will not God then do? Surely then it will look more agreeable to the design, and grandeur, and pregnancy of his love (if I may so call it) to give an eternal Son for us, than to make a Son on purpose for our relief. In such a dispensation as that of giving a natural, essential, eternal Son for us and to us, he will commend his love to us indeed; and what will not the God of love do when he designs to commend his love, and to commend it in the view of heaven, and earth, and hell, and when he will commend himself and recommend himself to us, and to our highest conviction, and also affection, as love itself? And what if it should appear at last (which I shall only offer to the consideration of the judicious) that the divine love, and particularly God’s love in Christ, should be the foundation of the glories of heaven, in the present enjoyment of those ministering spirits that comported with it, and of the salvation of this world, and of the torments of hell? This last will seem most strange. But what if therein it should appear not only that God is love to himself, in vindicating his own law, and government, and love, and glory, but that the damned ones are made so, or are so punished, (1.) Because they despised the love of God already manifested and exhibited. (2.) Because they refused to be beloved in what was further proposed and promised. (3.) Because they made themselves unmeet to be the objects of divine complacency and delight? If the conscience of the damned should accuse them of these things, and especially of rejecting the highest instance of divine love, and if the far greatest part of the intelligent creation should be everlastingly blessed through the highest instance of the divine love, then may it well be inscribed upon the whole creation of God, God is love.
