If and when you read this, you may possibly be as tired as a preacher usually is after the Lenten and Easter season. Sometimes we are inclined to forget that physical tiredness also has a very definite effect on the level of our mental, emotional, and spiritual life. Problems and perplexities which we can shake off ordinarily begin to loom out of all proportion to their real significance. If, therefore, you have some unusual anxiety or worry on your mind, you may ascribe it for the moment to the physical let down which comes after the stress and strain of the season of the church year in which our pastors are busier than at any other time."
