My wife and I love to leave the windows open - to air out the house, especially in the fall and spring when the temperature is just right. However, as it gets into summer… that’s when the flies start to come in. At first, all of the buzzing is miserable, but after a while, it doesn’t seem to bother us as much anymore. In today’s message, Pastor Mark teaches that sin is kind of like those flies. At first, it eats away at you and ruins a good thing. But after a while, the good thing is still ruined, yet it doesn’t bother you nearly as much as it used to. Today, if God is convicting you of a sin, maybe it’s time to close the windows.
