In Matthew 4:1-11, we read the debate between Jesus and the devil. The devil uses scripture in an attempt to sway Jesus, and Jesus responses, also using scripture. What is your back-up?
Perhaps you, too, respond to temptations by quoting scripture. Or, perhaps religious tradition, family tradition, or cultural tradition helps you stay on the path. If not, maybe you are an avid reader and the words of others help in difficult times.
Whatever your back-up may be, you will need something because none of us will escape temptation.
