I love this post because it reminds me of just a couple days ago how my wife (who claims to be an unbeliever), burnt a batch of home-made tortilla chips by turning on the broiler and neglected to check on them, thus creating an oil fire in the oven, which could've ended terribly had she not remained calm and found out what to do. Obviously as an unbeliever she fails to bring this mistake to our Most High and rebuild herself esteem through Him.
Instead she dwells on the mistake and digs herself deeper into a depression, until I step in and remind her that its merely a mistake and not truly her fault, I understand that the enemy comes in through us to steal, kill, and destroy, so I try to help her understand that she should not dwell on this mistake and just understand that it is a valuable lesson to learn from. God has a plan for her salvation (btw), I just need to relax and watch Him work. :D
Another great post OP. Shalom!
