"Keep your way far from her, and do not go near the door of her house." ESV
Who is she? She is the forbidden woman, of course. Some 3,000 year ago a man was warning his son against playing with fire. Indeed the warning is still relevant - perhaps more-so today than ever.
Whether you are a man or a woman, young or old, this warning is for you. Whether the danger looks like real adultery, or internet pornography, this warning is for you. This is a simple warning regarding sexual temptation: don't even get close to it! Don't go near the door to her house, let alone engage in a flirtatious conversation, or worse.
You know what this means for you. In this age of the sexual revolution, combined with incredible new technologies, we must heed this warning more than ever, for her door is wide open and ubiquitous.
