This is something I've wondered about a lot before, and I was wondering if there were any good resources for this. Certain attributes of God, such as merciful, loving, forgiving, etc. are active attributes that can't exist alone. Meaning that you can't be loving with nobody to love, you have to love someone else. So I'm wondering this: God existed alone for eternity before creating anything, so how can he be loving if he had nobody to love? Some people might say that he had foreknowledge of us or of the angels, and loved us based on that, but if he was only creating out of foreknowledge then where did that foreknowledge come from?
Basically, I don't understand how a single being alone in the universe can become loving with no other being to love, have any Christian scholars or philosophers looked into this? Are there any resources you could give me on the nature of God?
