Thanks for the comments Ben!
Yeah you are totally right. The whole Bible is full of stories of God and people interacting. I think I just needed to remind myself that I have a part to play in that.

I think also God obviously is God and doesn't need us in the sense that he won't exist without us. But even before we were created God did exist forever, but yet he still had community with the trinity so he was never alone. But if God exists partially to be known by us, to receive joy from being loved and worship by us then I think that opens God up to me. That I am important to him.

Desiring God by Piper is a great book that explores a lot of this stuff.
P.S. I love you too x :)
