A friend comes to you struggling to believe they are really forgiven. They keep becoming anxious and losing confidence about whether or not they are really a Christian when they seem to keep seeing sin in their life. What would you want to say to them?

"six months ago, several of molly's friends joined the trimtime fitness center. each of them participated in trimtime's weight-reduction and fitness regimen. all reported substantial weight reduction, and all are visibly slimmer. molly is convinced. she joins trimtime and enrolls in the program, hoping and expecting to see the same results. she is especially delighted to learn that trimtime had adjusted its program to make it even more effective in a shorter period of time." what is the feature in question/attribute of interest in this argument?
