I've been struck recently by the way insecurity manifests itself in different ways. Someone can appear classically insecure by appearing as a shrinking violet, not volunteering and putting themselves down. On the other hand others can manifest insecurity by talking a lot, never admitting they're wrong/not sure/in difficulty and generally appearing to be really confident.
What's going on there and what's a gospel-of-grace solution?
This article by Jon Bloom is good and I particularly like the bullet pointed list of how we can apply the Gospel to particular facets of insecurity. Worth a read.
