I have often heard the argument that God, in His existence being Trinity, has all the love to share amongst them all. God is satisfied with Himself, He is who He is.
Let me throw you an unanswerable question: what if God can be lonely? What if, in being a human, He has limited Himself to the things that He can access. What if Jesus was lonely, when He way praying and His disciples were sleeping in the Garden of Gethsemane?
What if, each day as God waits for us to spend time with Him, and as we continually forget about Him, what if, God is lonely - lonely without us?
(Post is inspired by a song in my IPod by Alanis Morisette - What If God Is One of Us?)
