John Welch, the holy and wonderful Scotch preacher, thought the day ill spent if he did not spend eight or ten hours in prayer. He kept a plaid (kilt) that he might wrap himself when he arose to pray at night. His wife would complain when she found him lying on the ground weeping. He would reply: “O Woman, I have souls of three thousand to answer for, and I know not how it is  with many of them!”
