Before I mention how we should approach unto and lie at this well-head of life, let me observe to you this one thing,—that when there is a general contagious disease (the plague, or the like), every man will look to his health and safety with reference to other occasions, but will be most careful in regard to the general contagion. Now, if forsaking this spring of life be the plague of the age, and the plague of the place where we live, and the plague of Christians, we ought to be very careful lest this general contagion should reach us.
