Yes, there are things we do not understand. But can anyone state, with any degree of certainty, that we will never understand something? Compare and contrast what we knew 2000 years ago to 200 years ago to 20 year ago. If the idea of God is defined by what we do not know, then in reality, Creationists have placed God in a small box that is getting smaller and smaller.
Just a small aside. I saw a Mike Peters editorial cartoon today of Ann Coulter taking the Ice Bucket Challenge and melting like the Wicked Witch of the West from the Wizard of Oz. My first thought was "I wonder is Bill O'Reilly has taken the challenge"?
For the record, I have not been challenged. If I am so challenged, I will take it and will also donate to a charity that hits closer to home for me, Multiple Sclerosis. Nothing personal ALS, just MS has more meaning for me. I usually donate to MS, Special Olympics, Vietnam Vets, and the American Heart Association annually. I encourage everyone to donate to a worthwhile charity, whether you dump icy water on your head or not or even if you don't film it and post it somewhere!
