“The eye being a tender part, and soonest hurt, how watchful is man by nature over that, that it take no hurt. So the heart, being a tender thing, let us preserve it by all watchfulness to keep blows from off it. It is a terrible thing to keep a wound of some great sin upon the conscience, for it makes a way for a new breach; because when the conscience once begins to be hardened with some great sin, then there is no stop, but we run on to commit sin with all greediness. 9.”
