Why in God's name?

I've heard people ask before why God decided to create human beings. Was he lonely? I've heard this question answered a couple different ways. Most Christians would say that God did not create us because he was lonely; that would imply that God is incomplete without us. The same people might say that the most selfless thing a perfect being could do would be to create other beings to enjoy his presence. I heard someone respond to that by saying, "Doesn't that make God really narcissistic?" Yeah, it sure sounds that way, but the God I know really is more giving than greedy.

I tend to think the truth is almost simpler. I think God created us because it's just who he is. He exists in relationship as Father, Son, and Holy Spirit, and he created us because he just loves relationships. Love loves to have an object to love. I prefer to think that God created us out of his incredible grace and has endeavored to love us and redeem us to himself because it is just his nature to love.
