There is great danger, yea, many times most danger, in the smallest sins... Greater sins do sooner startle the soul, and awaken and rouse up the soul to repentance, than lesser sins do. Little sins often slide into the soul, and breed, and work secretly and undiscernibly in the soul, till they come to be so strong, as to trample upon the soul and to cut the throat of the soul.
