In his book The Christian Atheist, Craig Groeschel offers a litmus test of sorts that might shed a little light on your relationship with God. He writes:

If you call me "Pastor Craig," chances are you might know a little about me. You know what I do, maybe you've heard me speak, and maybe you're familiar with some of my favorite topics and my up-front personality. But your use of my title doesn't mean that you know me personally.

You might just call me "Craig," and I'd usually assume that you know me even better. My friends call me Craig. We're close.

Then there are those who possess exclusive rights to a few specialized, far more intimate forms of address. These are the six beautiful, small people, very dear to me, whom I allow to climb up in my lap. They rub their hands on my face and say things like "You need to shave" and "You're the best" and "Can I have some candy?" They call me "Daddy." The name reveals the intimacy.

What do you call God? Your answer may be a clue to how well you know him. Or don't.
