I did not say it was a sin to drink. You need to read my post and not add to it.
While irritable bowel/Crone's disease is not sin someone could let it develop into stress and that would be sin.So if this causes her long term sin she needs to repent. I also have what is called dumping having to go 5 or 6 times a day and it also causes accidents as it is most always diarrhea. While I would that I did not have this it does not cause me stress because I accept it in the Lord. So again if she has stress over this then she needs to confess and forsake and accept.
1thess 5:18
In every thing give thanks: for this is the will of God in Christ Jesus concerning you.
Do this and stop sinning.
So my friend worrying about pooping in her pants when she's on a date is wrong? OK - I'll let her know.
