We consider that His blood absolves us from the guilt of what we sinfully used to do so we do such things no more, once we are sure they are wrong but also sure that the sacrificial covering of His blood is for past sins and sure that to continue wantonly to repeat those sins mocks that sacrifice. Sins we later learn are sinful as time goes on, we set aside too, as and when we recognise them, understanding and believing that the blood pays for the guilt of these as well.
