True enough
Well, assuming you agree the God's love (agape) mean a volition to favor ..... I don't see why putting billions of people in hell is favoring me. Now, not sending us to hell is a show of love to us, but not sending someone to heaven is not doing me much of a favor (showing me love) unless you stretch the definition to somehow being a minute favor somehow to me and you.
I'd say "yes". But the subject at hand is: Is the act of God sending people to hell a show of His love? I think it is a show of His wrath which is the opposite of "love".
Is the act of God "allowing" someone to kill all of one's children also a demonstration of God's love (favor)?
