The internet is abuzz with talk of the "fatal fridge"; a break-room refrigerator was in need of being cleaned, so one woman took it on herself to throw away the old food inside. The fridge had been unplugged "for some time," and the contents were so corrupt that all 325 people who worked there needed to be evacuated, 23 became sick and 7 were hospitalized. The woman who cleaned the refrigerator didn't even notice; she had severe allergies, and was unable to smell.
It's hard to know for sure (after all, we are talking about California), but it's still not too likely that one of the employees brought a Tupperware container of mold for lunch. So how did this happen? The food in the refrigerator was neglected and ignored, and some nearly undetectable microscopic spores began to spread. Without anybody realizing, it slowly grew until it became so overwhelming that it made national news.
In the same way, nobody wakes up one day suddenly deciding to turn away from God. People let the cares of the world choke the Word of God (Luke 8:14) until they entangle them and overcome them (2 Peter 2:20-22). If this is starting to happen to you, then "clean your house" now, before it's too late; don't let a little problem grow to an epidemic.
