We know that whosoever is born of God sinneth not; but he that is begotten of God keepeth himself, and that wicked one toucheth him not.
The reason the saints of God do not sin is because our sins have already been put under the cleansing BLOOD Crist shed for us on the Cross. We are cleansed by HIS blood.. Our sins are not held against our account..
Does this give us license to willfully sin? NO !!! It just points outhow greatthe grace of GOD truly is toward tose who love HIM and are called by HIS NAME !
