In a world of love, you literally choose to accept the contents of reality without imagining anyone being removed from that set.
In the set of love, one can use the like/dislike system to establish personal preferences, and eventually personality. And as you know God is love. This establishes character in a stable set.
Life happens in the set of love.
If a personality is not built in the set of love, it is not stable. If it is built on hate, even on conditional hate, it is built on the ability to remove something from reality. Basically imagining things not existing. So it would be basing personal preferences on something that is unstable, or that does not exist.
For instance, when you say I hate photographers, you’re really thinking I prefer reality without photographers. But it’s not realistic. Photographers exist. So next time you’re around a photographer, you’ll hate it. And be probably miserable. Because you will exist outside the set of love.
Grudges are a great example of how hate can make unstable realities. If you have a grudge against someone, and are at a party together. All is well until you run into that person. And things get awkward. You were fine until this hate entered your realty. Now you wish either they weren’t here or you weren’t here, but you’re stuck. And instead of enjoying yourself, you’re thinking about how either you want them to leave or you want to leave yourself.
If you hate the way you feel, you are distancing yourself from God. It seems trivial, and I’m not saying you need to like the way you feel. But dislike is not hate. When you got married, you promised in sickness and in health. God wants the same thing.
So if we live inside the set of love, and develop logic and personalities around our identity in this set, we can love God in more realities, and thus imagine more realities with God, and thus love Him better.
