Hi there, could you rephrase /say in other words/ "When you have sinned grievously, the devil is waiting." I need to translate that in my native language but I can't get the meaning. I'd like to thank Judith for the previous answer. It was of great help for me.

Well its baisicly saying that when you a really bad deed you will go to hell for it(in a nutshell anyway)

The devil is very well known to be waiting and wanting more followers.

People that commit mortal sins are quickly
