Have you noticed how much we speak about God, rather than to God? Sermons, Bible studies, testimonies of believers...all about what God has done. To put it grammatically, we talk about God in the third person, the same impersonal way we talk about the weather, taxes, what have you.
So I found it strange years ago when I began reading St. Augustine's "Confessions" for the very first time. "Great art Thou, O Lord, and greatly to be praised; great is Thy power, and Thy wisdom infinite. And man wants to praise You, man who is only a small portion of what You have created..." and on and on Augustine goes, second person, talking directlly to God.
I'm not writing here about prayer, about intentional times of talking to God, but rather about those times when we're thinking of whatever we happen to be thinking. I've put myself under the mild discipline of phrasing those quiet, usually hum-drum thoughts in the second person, directly to God. The result of that little grammatical recasting of my mundane thoughts has been a tremendous advance in my spiritual life. I know His presence more than when I put Him off in the third person. Try it; He'll like it!
