Sometimes we simply can lose interest.
When something is new and fresh, it's easy to be excited and captivated by it. A new romance. A new phone or computer. A new adventure in life. But, like taste buds, we can find ourselves less enthused with every bite. The first taste was amazing, but after the 25th, we're accustomed to the flavor and it becomes just another bite. We still like it. Don't get me wrong. It's just not exciting anymore.
This concept can be tricky when it comes to long term things in life. Like marriages. Like our friendship with God. Things that we want to stay exciting, but somehow can be dulled with time.
Some have a disposable attitiude: If your gum loses favor, you spit it out and find a new piece to chew. Others don't take that perspective and realize that it might not necessarily be such a hopeless situation. Like a fire, it might just need an extra log to get it going again. It's not dead, it just needs to be helped along a bit.
I love the song Escape (the Pina Colada Song). Ok, well, not the fact that the married couple goes placing personal ads about themselves to find new love. But, the idea that what they were looking for had been there all along! He answered his own wife's ad as he went looking for something exciting. He had no idea how exciting things could be with her. Maybe he didn't realize she was even interested in making things exciting again.
They both realized they didn't need someone different. They just needed to rediscover each other.
