There are a lot of things I can't fully wrap my mind around, but I'm certain that is how it is supposed to be. I'm very analytical for a "creative type;" I have a background in math and I love understanding data. Some things, though, are best left with a little bit to be explained.
I'm currently reading Donald Miller's Blue Like Jazz, and this piece came as a response to Miller making a case for awe and wonder:
Too much of our time is spent trying to chart God on a grid, and too little is spent allowing our hearts to feel awe. By reducing Christian spirituality to formula, we deprive our hearts of wonder.
When I think about the complexity of the Trinity, the three-in-one God, my mind cannot understand, but my heart feels wonder in abundant satisfaction. It is as though my heart, in the midst of its euphoria, is saying to my mind, "There are things you cannot understand and you must learn to live with this, you must learn to enjoy this."
