You little know what you have done, when you have first broke the bounds of modesty; you have set open the door of your fancy to the devil, so that he can, almost at his pleasure ever after, represent the same sinful pleasure to you anew; he hath now access to your fancy to stir up lustful thoughts and desires, so that when you should think of your calling, of your God, or of your soul, your thoughts will be worse than swinish, upon the filth that is not fit to be named. If the devil here get in a foot, he will not easily be got out.

The more perfect the sight is the more delightful the beautiful object. The more perfect the appetite, the sweeter the food. The more musical the ear, the more pleasant the melody. The more perfect the soul, the more joyous the joys of heaven and the more glorious that glory.
Naturally, men are prone to spin themselves a web of opinions out of their own brain, and to have a religion that may be called their own. They are far readier to make themselves a faith, than to receive that which God hath formed to their hands; are far readier to receive a doctrine that tends to their carnal commodity, or honor, or delight, than one that tends to self-denial.
