I think that must be how God feels toward us when we indulge in sin. He knows how filthy it is and how bad it is for us, and He is saddened that we choose to remain in it. Unlike the children of Belen, we have a choice. God has saved us and brought us into His "Boat". We don't need to remain in the filth of sin we were born into. When we choose to swim in it after our eyes have been opened to it's filth, we are like fools who would put on their nicest clothing and dive into sewage.
I find myself thinking of this a lot lately as God has confronted me about some areas of sin in my life. I am going through Romans, and I am being awakened to sins I didn't realize I committed. If I remain in them, I sadden God, because He has so much better for me than the sewer I was pulled from.
