The key is to avoid despair; sadness hits all of us but we still live by faith. Sometimes my unworthiness makes me wonder how I represent my faith. St. Paul repented from his past & boldly said he is not ashamed of the Gospel ( Romans 1:16).
Surely I dare not compare myself to St. Paul. On a lower level, amidst my sins, I feel some realization at times. As long as I know my sinful state, I think it helps me avoid delusion, to keep the golden rule ( Matthew 7:1-12), remember the commandments (Matthew 22:36-40) in expressing myself. I feel that I also might be blessed to inform someone better than me who could otherwise do something better than I would do with it. I also know I spout stupidity sometimes.
