Despite my best efforts, I continue to receive junk mail. The goal of those who solicit us with junk mail is to entice us, whet our appetite, pique our interest, sway our opinions, so we will accept or seek out what they're offering. If they can just get us to open the envelope or read the pamphlet, card, or insert, they may be successful in their pursuit. Some people appreciate receiving mail that solicits them for money, various products and/or services, participation in groups, etc. After all, it's possible something about which they weren't aware turns out to be of interest to them. Sometimes, it might be something they wouldn't be interested in under normal circumstances, but it reaches them at a time they're particularly vulnerable.
There's another type of junk mail we may receive--that presented to us via gossip, negativity, backbiting, discouragement, etc. Sometimes, we see it for what it is and immediately discard it. But what about when we're feeling vulnerable--for example, when someone hurts us and we hear gossip about them, or when we're struggling while pursuing a goal and someone discourages us? Acquiescing to this type of junk mail has a cost. It can permeate our spirit; cause us to make unwise decisions; and/or change the way we feel about someone/something. Personally, I try to treat it like any other junk mail and discard it. Otherwise, I'm allowing something worthless to distract me, and that has the possibility to detract from my joy.
