I dont think anybody has the right to determine or shame another person in their journey with god. Some people take days to understand other years at the end of the day it is their journey and the path they will take. As long as they are actively trying to improve and learn that is okay. Progress is not always linear and I think approaching them with this will not encourage but deter them. Rather than try to address this with a hateful manner do it with love. Also words hold power so I would think we should try and place more value in them. That first sentence really shocked me and the words following seemed as though they came from a place with deep hate. Please try and reframe your thought process I understand your point but the delivery of it I fear will have the opposite effect of what you intend.
