Recently I had to read a paper by Fritz Guy, in a book advocating a non-Calvinistic, Arminian position, called The Grace of God, The Will of Man. In Guy's chapter (called "The Universality of God's Love"), he describes the Divine love as "God wills what is best for every created entity". Guy upholds this definition, and essentially says that God must do everything within his (limited!) power to achieve the best for every single created entity, there can be no selectiveness. But this does not hold up to Scriptural scrutiny, as nice as it might sound.
For a start, such a definition immediately breaks down when one considers the devil and his demons. God gives them no opportunity for salvation at all (cf. Heb. 2:16), and they are not treated the same as humans. Already God is selective in his love and doesn't seem to "will what is best for every created entity". Further, the Scriptures are unambiguous that God is also discriminating and selective in some ways he shows his love towards mankind, such as in his loving selection of Israel rather than other nations (Deut. 7:7-8; 10:15), or in reference to Jacob and Esau (Mal. 1:2-3; cf Rom. 9:10-13). And this is just dealing with very clear texts, without specifically even getting into the whole issue of individual election unto salvation, or of considering the implications of real experience (like the fact that some people never hear the gospel, or that some people might die from famine, drought or disease, but others do not, etc).
Therefore to flatten out God's love to say there can be no particularity at all is to impose a false conception onto the Scriptures, rather than let them speak for themselves. Better to say with J. I. Packer that there is both particularity and universality in God's love: "it appears, first, that God loves all in some ways..., and, second, that he loves some in all ways... This is the clear witness of the entire Bible" (quoted out of his article entitled "The Love of God: Universal and Particular").
