That's until it belongs to God and then he cleanses it!
No He doesn't. You might think that you "devotions" cleanse your heart, but you are mistaken. On regeneration He removes the heart of stone and replaces it with a heart of flesh. Yes it is a clean heart, but it's a new heart. If you had this experience you wouldn't talk about such stupidity.
it's just like this nonsense about come to Jesus and He will give you a new life. NO He doesn't. He gives that which is DEAD to be alive in Him.
