What is God's purpose?

The best response that I have to this is found in scripture:

God said to Moses, "I am who I am. This is what you are to say to the Israelites: 'I am has sent me to you.'" (Exodus 3:14, TNIV)

God is.

God exists in relationship eternally, with creation, humanity and individuals. Perhaps God's purpose is to love and be loved in return.

What would you add to this response?

I recently met with a congregant who shared some deep questions with me. I asked for permission to share them on this blog to more broadly share my response.
