I don't believe it does, and I believe that were it true God indeed would be a respector of persons. "You did this and he did not, therefore I will choose you and not him."
You two are again arguing over whether God regenerates due to irresistible grace before we believe or whether we believe due to prevenient grace and then are regenerated. Answer that question and you win the prize.
No, not really. While that is related, the core issue right now is why God loves some men differently than others. I don't think it is at all Scripturally tenable to state that God loves all men the same in every sense. The question then becomes what is the extent of the difference in His love for some over others and what (if any) objective basis is there for that difference.
Faith.
