2 Peter 3:17-18
You therefore, beloved, seeing you know these things before, beware lest you also, being led away with the error of the wicked…
There are evils which give warning of their coming. Drunkenness does not seize upon a man suddenly. It gives warnings often and many. Avarice, and a number of other vices, can be detected long before we are within their reach. There are infallible indications by which we may be warned. The approach of vice is like the approach of the rattlesnake. This horrible reptile, one of the most venomous of serpents, warns man involuntarily against its formidable presence. At the end of its tail there is placed a rattle, which consists of a string of hollow, dry, trod semi transparent bones, which constantly clatter against each other as the reptile moves, with a hoarse, dull, echoing sound. The bony rings increase in number with the reptile's age, and it gains an additional one, it is said, at each casting of the skin. The warning which it is thus compelled to give of its approach enables those who hear to escape an awful death. Happy are those men whose ears are open to the warnings which social monsters, far more horrid than even the rattlesnake, in like manner invariably give of their presence and movements, and, profiting thereby, manage to escape.
