Good one you got her (...again). Flippant remarks and subtle reprisals of her dignity are a little counterproductive. An acute anxiety on this subject is prompting her to return to this forum seeking genuine responses from someone who has experienced this same dilemma and possibly some advice on how to resolve it. Instead you insert your own personal agenda and subtly bring up specific past transgressions already resolved that are irrelevant to the current question being posed. Don't suggest that she need repent (...again) implying that this sin is as grave as the past sins you're obviously keeping track of. This is already causing her anxiety and a sense of condemnation but it should not be experienced as gravely as the past sins you're referring to. I'm not saying give positive reinforcement but maybe promote her God-given ability to overcome this temptation and counsel with her bishop. Careless little discrepancies in your speech can cause people with serious anxiety disorders to further condemn themselves and have self-defeating thoughts of failure. It can be overwhelming and they give up altogether or leave the church. Take this extremely thought provoking story of Zeezrom into account; Alma 15:3-12. Had Alma and Amulek phrased their response to this man as you have I'm sure there would have been a negative outcome. 6 And it came to pass that Alma said unto him, taking him by the hand: Believest thou in the power of Christ unto salvation?7 And he answered and said: Yea, I believe all the words that thou hast taught. 8 And Alma said: If thou believest in the redemption of Christ thou canst be healed. (Alma 15:6-8)
