God gives to the righteous and the unrighteous. In fact God's love is unconditional, impartial. God also gives in abundance, more than enough for the whole world (just like the basket of fish and bread that fed the multitude).
But God's love is not like our love, borne out of a need, desire, fear, emotions, desire to be safe. God has no such needs. He saves those who are righteous in His eyes and not because He "likes" them. It's not an emotion, or opinion: it's a fact: those who are righteous in His eyes are truly righteous even if we don't see them as such.
Likewise, the wicked are lost because they remain unrepentant and God see them as such, not because He doesn't "like" them.
For things like rain or sunshine, this is certainly true. It is one kind of grace, and in this sense it can be said that God loves the whole world. However, this is not the case with saving grace. That only goes to those God has already chosen:
Rom 9:8-18 : 8 In other words, it is not the natural children who are God's children, but it is the children of the promise who are regarded as Abraham's offspring. 9 For this was how the promise was stated: "At the appointed time I will return, and Sarah will have a son." 10 Not only that, but Rebekah's children had one and the same father, our father Isaac. 11 Yet, before the twins were born or had done anything good or bad in order that God's purpose in election might stand: 12 not by works but by him who calls she was told, "The older will serve the younger." 13 Just as it is written: "Jacob I loved, but Esau I hated."
14 What then shall we say? Is God unjust? Not at all! 15 For he says to Moses, "I will have mercy on whom I have mercy, and I will have compassion on whom I have compassion." 16 It does not, therefore, depend on man's desire or effort, but on God's mercy. 17 For the Scripture says to Pharaoh: "I raised you up for this very purpose, that I might display my power in you and that my name might be proclaimed in all the earth." 18 Therefore God has mercy on whom he wants to have mercy, and he hardens whom he wants to harden.

I have no idea why God chooses some over others. I just know it wasn't based on points earned. :) Those who are righteous in His eyes are only those who are declared righteous SOLELY by the work of Christ.
