"Covering up our faults and failures is an involuntary reflex" -Nancy DeMoss from Seeking Him
Our sins and failures can also be an involuntary reflex, a habit of sort, a bad one. Do you ever have that one thing that you hate to do and you keep doing it? You don't even WANT to do it any more, but it calls to you. You're compelled...and then you do it. Again. Then you wanna cover it up.
King David covered up his sin, then led to many other ones. He writes of how his bones wasted away, God's hand was heavy upon him, and his strength was dried up. He deteriorated physically, emotionally and spiritually. I know this feeling...where walking around in your own body seems too heavy, too burdensome. This makes me think, my bones feel sore, my shoulder's feel heavy and my strength dried up because I also have sins covered up. Ones I fear to even admit to myself....or even begin to know what they are.
