If you yield to Satan in the least, he will carry you further and further, till he has left you under a stupefied or terrified conscience: stupefied, till thou hast lost all thy tenderness. A stone at the top of a hill, when it begins to roll down, ceases not till it comes to the bottom. Thou thinkest it is but yielding a little, and so by degrees are carried on, till thou hast sinned away all thy profession, and all principles of conscience, by the secret witchery of his temptations.
