Thus Satan leads poor creatures down into the depths of sin by winding stairs, that let them not see the bottom whither they are going. He first presents an object that occasions some thoughts; these set of fire the affections, and they fume up into the brain, and cloud the understanding, which being thus disabled, Satan now dares a little more declare himself, and boldly solicit the creature to that it would even now have defied. Many who at this day lie in open profaneness, never thought that should have rolled so far from their profession; but Satan beguiled them, poor souls, with their modest beginnings. O Christians, give not place to Satan, no, not an inch, in his first motions. He that is a beggar and a modest one without doors, will command the house if let in. Yield at first, and thou givest away thy strength to resist him in the rest; when the hem is worn the whole garment will ravel out, if it be not mended by timely repentance.
