“There is no one in the entire universe who, having received that love, can ultimately reject it.”
So, what are you saying? Did God not love Satan? Did Satan not reject Him? Did God lie when he said Satan would have to be cast into the Lake of Fire?
If we have free will, we can reject God’s love. If we can’t reject God’s love, then we don’t have free will, so we are automata, in which case, we cannot love God, and therefore, we cannot obey His commandments. I hope you can see where the train of your logic is leading...
God's love is greater than YOUR train of logic. Satan rejected God's love temporarily, not forever. The proper logic is to start with the absolute power of God's love and work from there. Anything else is anathema. God's love is either all powerful, because it IS God, or it's not. There's no third way. And succumbing to that infinite love GIVES freedom, it doesn't remove it. Do you worth about your precious free will when it comes to sudden illness, early death, or hardship? No. Then you're all about the "grace of God." But infinite love puts you in jail? LOL!
You need to do some serious contemplation. Sin and hell are mere blips to God. Infinite love is the point, and it goes on forever.
