A few weeks ago, something was smelly in our room. We couldn't see where the smell was coming from, but we were certain something was rotten because we could all smell it. We searched and finally, we found a bird's nest under our AC unit. There were dead birds.
We can try to hide our sins, but sooner or later, they will surface. Just like the foul smell in our bedroom. It was because of its stench that we found where the smell was coming from. So in our life, as we try to cover up our sins, the stench of our sins will eventually caught up with us!
