If I throw a piece of ice in the sidewalk it won't make the news. No one is in danger of losing their power or having tree branches fall on their roof and car. It's when the winter storm hits and ice builds up on the trees that we are in danger. The combined accumulation threatens our safety and comfort.
Sin is dangerous and threatens our well being, but when it is allowed to accumulate it is extremely harmful. The combined effects of lying, gossip, lust, and pride can threaten to topple our families, destroy our reputation, and diminish our influence. The best way to prevent that additive effect is to regularly clean out our lives through confession and repentance. Don't allow it to build up to the point of catastrophic damage or you may find it too big of a mess to clean up.
