Satan is so wily, his agents so surround us, their designs are so masked, their language so plausible, their manners so insinuating, their appearance often so imposing, their arguments so subtle, their activity so unwearied, their insight into our weaknesses so keen, their enmity against Christ and His gospel so implacable, their lack of all principle and all honesty so thorough, that the net may be drawing around us, before we have the slightest suspicion of these infernal plots being directed against us!
