Seriously, the thought came when reading these verses, "why would they have to be given specific instructions on relieving themselves?"
Obviously, this isn't a very sweet subject, but one God needed to touch upon. To hand down laws regarding fecal matter. These laws were to be followed as one way of keeping the camp free from diseases and unpleasantness.
To keep the camp holy because God strolled through it.
I then begin to wonder - how is my camp? Just like human waste, sin doesn't offer up a sweet fragrance to the Lord. What worldly fecal matter am I putting into my mind, my heart? What "spiritual weapon" am I carrying with me at all times?
As His, our bodies are a temple in which The Holy Spirit lives. Our ABBA. He lives within us. He strolls through our "camp" and we are instructed to "keep our camp holy".
God in His wisdom created the layers of earth as a filter for unclean matters, before entering into our drinking source. Today, there are many third world countries where it is completely normal to relieve themselves wherever and whenever the urge hits. These countries are riddled with diseases that can be traced back to this unhealthy practice.
Much like a person becomes so far removed from keeping their spiritual camp clean.
Through Scripture our ABBA teaches us a sin is a sin. There are no greater or lesser levels. Any sin separates us from Him for He is Holy and can not be a part of sin. Any sin. And yet, so many of us have decided it is okay to live in a camp allowing sin within the perimeter. And when living close to sin, it will seep into your being, just as the waste from an outhouse sitting too close to the well or the running water.
For we are His spiritual camp in which He resides. His spiritual camp in which He strolls.
