Today I was reminded, in a small way, of just how replaceable I am. About 20 minutes prior to the close of my morning sermon my heart started racing, like I was in the 4th quarter of a basketball game. About 10 minutes before close, with my heart still racing, I started feeling very dizzy. As I was concluding with a prayer, I remember thinking: 'just don't faint'. Sadly, I was so focused on not fainting that I forget to bring a family up who were prepared to come into membership.
Worse yet, I don't even remember what I said during the last 10 minutes of my sermon. My wife assures me there was nothing heretical---though I did somehow manage to insert a quote by R.C. Ryle (mis-referenced as being from a Puritan book from the 1600's) on prayer that really had nothing to do with my sermon on the walls of Jericho (Josh 6/Heb 11:30). Oh well, one cannot be too disturbed by discovering his "default mode" when disoriented is to randomly quote Ryle.
I'm not too alarmed, and I have no known heart conditions. But, at my wife's insistence I will make a visist to the doctor this week and go through a bunch of tests (I assume).
