"I am not an enemy to pleasure; but I am an enemy to sin."

"I have not much time to spare for trifles."

"I do not think that I have ever spent an hour in my life, from the age of twenty-one to this day, without employing it in some useful way."

"I am not afraid of being accounted an enthusiast. I am afraid of nothing but sin."

"Sing lustily and with a good courage. Beware of singing as if you were half dead, or half asleep; but lift up your voice with strength."
