Think about that! Not many today think about a "covering". It isn't necessarily a part of our modern culture. In reality, even in clothing today there's little if any modesty, much skin is revealed. I can see a spiritual portrait here of our sin sick and morally depraved society. Can you see this condition?
There are many examples in the Word of God that shows the blessings of being covered in Christ as well as the Father's displeasure of those who seek anything and everything but Him.
In Exodus 12 they were instructed to put lamb's blood upon the 2 posts of every house in order that the spirit of death or "the destroyer" may pass by, leaving all inside this protective covering safe. Pretty remarkable! This was a portrait of what Christ does for us who are His!
