God's love for His people alone

Calvin, Sermons on Deuteronomy, Sermon, 28, 4:36-27, p., 167..
"It is true that Saint John says generally, that he loved the world. And why? For Jesus Christ offers himself generally to all men without exception to be their redeemer. It is said afterward in the covenant, that God loved the world when he sent his only son: but he loved us, us (I say) which have been taught by his Gospel, because he gathered us to him. And the faithful that are enlightened by the holy Ghost, have yet a third use of God's love, in that he reveals himself more familiarly to them, and seals up his fatherly adoption by his holy Spirit, and engraves it upon their hearts. Now then, let us in all cases learn to know this love of God, & when we be once come to it, let us go no further.

Thus we see three degrees of the love of God as shown us in our Lord Jesus Christ. The first is in respect of the redemption that was purchased in the person of him that gave himself to death for us, and became accursed to reconcile us to God his father. That is the first degree of love, which extends to all men, inasmuch as Jesus Christ reaches out his arms to call and allure all men both great and small, and to win them to him. But there is a special love for those to whom the gospel is preached: which is that God testifies unto them that he will make them partakers of that benefit that was purchased for them by the death and passion of his son.

And for as much as we be of that number, therefore are we are double bound already to our God: here are two bonds which hold us as it were straightened unto him. Now let us come to the third bond, which depends upon the third love that God shows us: which is, that he not only causes the gospel to be preached unto us, but also makes us to feel the power thereof, not doubting but that our sins are forgiven us for our Lord Jesus Christ's sake..."
