With my mind divided and torn to pieces by so many problems, how can I meditate or preach wholeheartedly without neglecting the ministry of proclaiming the Gospel? Moreover, in my position I must often communicate with worldly men. At times I let my tongue run, for if I am always severe in my judgments, the worldly will avoid me, and I can never attack them as I would. As a result I often listen patiently to chatter. And because I too am weak, I find myself drawn little by little into idle conversation, and I begin to talk freely about matters which once I would have avoided. What once I found tedious I now enjoy.
