Manton:
The love of John 3:16 antecedent to electing love:1:
1) The ground of all that love God beareth to us is for Christ’s sake. There is indeed an antecedent love showed in giving us to Christ, and Christ to us: John iii. 16, ‘For God so loved the world, that he gave his only-begotten Son That whoso ever believeth in him should not perish, but have everlasting life.’ The first cause of Christ’s love to us was obedience to the Father ; the Son loved us, because the Father required it ; though after wards God loved us because Christ merited it. All consequent benefits are procured by the merit of Christ. The Father, that is first in order of persons, is first in order of working, and can have no higher cause than his own will and purpose. And besides, there is an obligation established to every person. Absolute elective love is the Father’s property and personal operation; but then his eternal purpose is brought to pass in and through Jesus Christ. Thomas Manton, “Sermon 40″ in Works 11:76.
The love of John 3:16 is the love of benevolence:
1) Strictly, it is taken for our complacency and delight in God. Divines distinguish of a twofold love; a love of benevolence and a love of complacency. The love of benevolence is the desiring of the felicity of another; the love of complacency is the well-pleasedness of the soul in a suitable good. God loveth us both these ways; with the love of benevolence: ‘For so God loved the world. &c., John iii. 16 ; with the love of complacency, and so ‘ The upright in the way are his delight.’ But we love God with but one of these, not with the love of benevolence; for he is above our injuries and benefits, and needeth nothing from us to add to his felicity ; therefore we cannot be said to love him with the love of benevolence, unless very improperly, when we desire his glory; but we love him with a love of complacency when the soul is well pleased in God, or delights in him, which is begun here, and perfected hereafter. This is spoken of, Ps. xxxvii. 4, ‘Delight thyself in the Lord, and he shall give thee the desires of thine heart.’ And it is seen in this, when we count his favour and presence our chiefest happiness, and value an interest in him above all the world, Ps. xvi. 6. 7, and Ps. iv. 6, 7 ; and when we delight in other things, as they belong to God : Ps. cxix. 14, ‘ I will delight myself in thy commandments, which I have loved.’ Thomas Manton, Sermons on 2 Corinthians 5, in Works, 13:141.
The love of John 3:16 is a love to the creature:
3) There fore, ‘herein is love;’ that is, this is the highest expression of God’s love to the creature, not only that ever was, but can be; for in love only God acteth to the uttermost: he never showed so much of his power and wisdom, but he can show more; of his wrath, but he can show more; but he hath no greater thing to give than himself, than his Christ. At what a dear rate hath the Lord bought our hearts I He needed not; he might have made nobler creatures than the present race of men, and dealt with us as he did with the sinning angels; he would not enter into treaty with them, but the execution was as quick as the sin; so the Lord might utterly have cast us off, and made a new race of men to glorify his grace, leaving Adam to propagate the world to glorify his justice; or, at least, he might have redeemed us in another way, for I suppose it is a free dispensation, opus liberi consilii. But, John iii. 16, ‘God so loved the world, that he gave his only-begotten Son.” He took this way, that we might love Christ as well as believe in him. God might have redeemed us so much in another way, but he could not oblige us so much in another way; he would not only satisfy his justice, but show his love. It was the Lord’s design, by his love, to deserve ours, and so for ever to shame the creature, if they should not now love him. Oh ! think much of this glorious instance, the love of God in giving Christ, and the love of Christ in giving himself. Thomas Manton, “An Exposition with Notes, Upon the Epistle of Jude,” in Works 5:80-81.
