A person who sins is like a baby in a dirty diaper. We all do it, but God still loves us anyway, even though sin makes us stink to God. When we cry out to Him for help, He changes us, and removes the filth from our lives. Then we do not stink any more. Until we sin again.
Been changing a lot of poopy diapers lately, and thought of that. Whenever my little boy has a messy diaper I still love him. I don't get rid of him because he stinks, I clean him up and give him a new diaper.
